problem with SINR

[Marcos Costa]

i'm new to ns3 and i need to collect the sine, i'm using lena-x2-handover-measures, i researched the group about it, but the code i can get is not working

void NotifyUeReport (Ptr<OutputStreamWrapper> stream, std::string context, uint16_t cellid, uint16_t rnti, double rsrp , double avsinr){

std::cout << context

<< " eNB CellId " << cellid

<< " RNTI " << rnti

<< " RSRP " << rsrp

<< " SINR " << 10*log(avsinr)/log(10)

<< std::endl;

*stream->GetStream() << Simulator::Now().GetSeconds() <<"\t"<<rnti<<"\t"<<rsrp<< "\t" << 10*log(avsinr) / log(10) <<std::endl;

}

------------------------------

AsciiTraceHelper asciiTraceHelper;

Ptr<OutputStreamWrapper> stream = asciiTraceHelper.CreateFileStream ("ueReport.txt");

--------------------------------

Config::Connect ("/NodeList/*/DeviceList/*/LteUePhy/ReportCurrentCellRsrpSinr",

MakeBoundCallback (&NotifyUeReport, stream));

when I run I get the error:

msg="Could not connect callback to /NodeList/*/DeviceList/*/LteUePhy/ReportCurrentCellRsrpSinr", +0.000000000s -1 file=../src/core/model/config.cc, line=923
terminate called without an active exception

You were missing one parameter. Use the following code:

void NotifyUeReport (std::string context, uint16_t cellid, uint16_t rnti,double rsrp , double avsinr, uint8_t k)

{
        std::cout << context<<std::endl;
        std::cout<<Simulator::Now().GetSeconds()<<"\teNB CellId="<<cellid <<"\tRNTI="<<rnti<<"\tRSRP="<<rsrp
        <<"\tSINR="<<10*log(avsinr)/log(10)<<std::endl;

}

And a small addition in the Config::Connect 

Config::Connect("/NodeList/*/DeviceList/*/$ns3::LteUeNetDevice/ComponentCarrierMapUe/*/LteUePhy/ReportCurrentCellRsrpSinr",MakeCallback(&NotifyUeReport));

It should work now.

Hope it helps.

Thanks Dr. Kiran, it worked.

A question, do you know how to use snr and rsrp data to generate graphs?
