Re: Wavecom W Code Digital Data Software Decoderl
Lorean Hoefert
Without a doubt, decoding digital signals at the software level has grown in recent years, easily supplanting the hardware decoders, since software packages can be updated and are generally free of hardware constraints. These packages run the gamut from free to the ultra-expensive - and often with the jump in price, you get more complete analysis tools, which may not necessarily be useful for someone starting out.
PC Software Decoder
The W-CODE is a software decoder of the well known WAVECOM line of decoders.
The W-CODE software is designed to work with your existing equipment -no proprietary hardware required. It allows seamless integration with SDR (Software Defined Radio) receivers with IQ data or digital audio outputs. One client license provided with each software package (Multiple licenses on request). W-CODE provides all functions required to analyze, decode and process radio data communications throughout the spectrum (HF, VHF, UHF, SHF).
These features allow the system to be adapted to the client's requirements and applications.
The determination of signal characteristics is assisted by a large number of analysis and measurement functions operating over a wide range of signal parameters.
The implementation of complex systems for monitoring on a large scale is only limited by the number of decoders and the performance of the hardware and software.
The configuration of the system components can be completely adapted to the requirements of the customer.
A W-CODE decoder may be controlled from everywhere in the network and its output may be sent to one or more applications on the network.
In order to process the data output, control the decoder and the code parameters, ain integrated remote control interfac akllows easy control of the W-CODE from a customer applications.
The easy-to-use user interface with well structured pull-down menus allows an operator to become familiar with the W-CODE in a short time. A high degree of operator proficiency can quickly be achieved.
All of the integrated analysis tools contain many different methods and viewing options.
It assists the operator in analyzing the important signal parameters.
Exact measurements are easily made using adjustable cursors with associated numerical displays. Dynamic zoom functions allow magnification of details in any selected window. The scroll buffering feature makes it possible to move back and forward in signal history.
Real-time FFT functions with a fast display refresh rate are implemented. Powerful functions provide the tools for analyzing unknown signals.
A wide range of system default settings can be configured, e.g. input signal level, measuring interval, centre frequency and demodulator type.
For government agencies, and telecommunications authorities, the applications range from stationary monitoring of one transmission with a single system to fully automated broadband monitoring employing many systems.
Decoded data can be imported from third-party applications running on the same or another computer in the network.
Software generated time stamps may be automatically added to each line of decoded data to ensure precise backtracking of any signal
To compare the books further RM has 448 images of either Spectrum data, sonograms and such like whilst I struggled to find many in KF, but KF does have many decoder screenshots, which if this is what you want then fair enough.
Kligenfuss does have a huge amount of data on Meteorological Transmissions, well over 140 pages, including tables and decodes, though I found the layout of some of it not that great. This information is readily available online anyway as is all the data contained in both books when it comes to frequencies, callsigns, MMSI decodes etc.
A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which there are several types. Later, two-dimensional (2D) variants were developed, using rectangles, dots, hexagons and other patterns, called matrix codes or 2D barcodes, although they do not use bars as such. 2D barcodes can be read using purpose-built 2D optical scanners, which exist in a few different forms. 2D barcodes can also be read by a digital camera connected to a microcomputer running software that takes a photographic image of the barcode and analyzes the image to deconstruct and decode the 2D barcode. A mobile device with a built-in camera, such as a smartphone, can function as the latter type of 2D barcode reader using specialized application software (The same sort of mobile device could also read 1D barcodes, depending on the application software).
Barcodes became commercially successful when they were used to automate supermarket checkout systems, a task for which they have become almost universal. The Uniform Grocery Product Code Council had chosen, in 1973, the barcode design developed by George Laurer. Laurer's barcode, with vertical bars, printed better than the circular barcode developed by Woodland and Silver.[5] Their use has spread to many other tasks that are generically referred to as automatic identification and data capture (AIDC). The first successful system using barcodes was in the UK supermarket group Sainsbury's in 1972 using shelf-mounted barcodes [6] which were developed by Plessey.[6] In June 1974, Marsh supermarket in Troy, Ohio used a scanner made by Photographic Sciences Corporation to scan the Universal Product Code (UPC) barcode on a pack of Wrigley's chewing gum.[7][5] QR codes, a specific type of 2D barcode, have recently[when?] become very popular due to the growth in smartphone ownership.[8]
Barcodes are widely used in the healthcare and hospital settings, ranging from patient identification (to access patient data, including medical history, drug allergies, etc.) to creating SOAP Notes[21] with barcodes to medication management. They are also used to facilitate the separation and indexing of documents that have been imaged in batch scanning applications, track the organization of species in biology,[22] and integrate with in-motion checkweighers to identify the item being weighed in a conveyor line for data collection.
Barcodes are also used in some kinds of non-contact 1D and 2D position sensors. A series of barcodes are used in some kinds of absolute 1D linear encoder. The barcodes are packed close enough together that the reader always has one or two barcodes in its field of view. As a kind of fiducial marker, the relative position of the barcode in the field of view of the reader gives incremental precise positioning, in some cases with sub-pixel resolution. The data decoded from the barcode gives the absolute coarse position. An "address carpet", used in digital paper, such as Howell's binary pattern and the Anoto dot pattern, is a 2D barcode designed so that a reader, even though only a tiny portion of the complete carpet is in the field of view of the reader, can find its absolute X,Y position and rotation in the carpet.[23][24]
Like the keyboard interface scanner, USB scanners do not need custom code for transferring input data to the application program. On PCs running Windows the human interface device emulates the data merging action of a hardware "keyboard wedge", and the scanner automatically behaves like an additional keyboard.
Most modern smartphones are able to decode barcode using their built-in camera. Google's mobile Android operating system can use their own Google Lens application to scan QR codes, or third-party apps like Barcode Scanner to read both one-dimensional barcodes and QR codes. Nokia's Symbian operating system featured a barcode scanner,[27] while mbarcode[28] is a QR code reader for the Maemo operating system. In Apple iOS 11, the native camera app can decode QR codes and can link to URLs, join wireless networks, or perform other operations depending on the QR Code contents.[29] Other paid and free apps are available with scanning capabilities for other symbologies or for earlier iOS versions.[30] With BlackBerry devices, the App World application can natively scan barcodes and load any recognized Web URLs on the device's Web browser. Windows Phone 7.5 is able to scan barcodes through the Bing search app. However, these devices are not designed specifically for the capturing of barcodes. As a result, they do not decode nearly as quickly or accurately as a dedicated barcode scanner or portable data terminal.[citation needed]
A matrix code, also termed a 2D barcode (although not using bars as such) or simply a 2D code, is a two-dimensional way to represent information. It is similar to a linear (1-dimensional) barcode, but can represent more data per unit area.
Over the past decade, 2D QR codes have gained popularity in the authentication of different commodities including multimedia data. The QR code was introduced by Denso-Wave [15] in 1994 to keep track of vehicle parts. Ease of generation of QR codes with free software and the penetration of smart phones enabled with QR code readers have made them widely applicable in different fields including manufacturing industries, shipping, airline, healthcare, advertising, and entertainment. The QR codes encoded with patient's data on their wristbands enable the hospitals to identify the patients and administer appropriate clinical procedures. Medication lists, treatment plans, appointment dates, contact details, and referral information of a patient can be encoded into a QR code. A QR code based authentication scheme is proposed by Liao and Lee [16], as an alternate for one-time password authentication scheme, for a remote user to access services from a service provider.
