It will prepare you for a diverse range of exciting careers - not only in communications but also in management consultancy, project management, finance and government.

Our graduates have gone on to have rewarding careers in leading multinational communications companies, including Huawei, China Telecom, Toshiba and Intel. Some graduates follow a more research-focused career path, with a number of students going on to study for PhDs at leading universities.

Note that, I'm not asking for the mathematically rigirous literature; I'm aware I'll need to work with large dimensional random matrices and I'm familiar with the random matrix side of things (I'm a mathematcian), but I'd like to know something bit more basic and applicartion-oriented, for example, where those random matrices actually arise, how the models are formulated etc.

One of the most readable (imho) authors on the communication systems is Simon Haykin and the following book from him would probably address most of the issues you would encounter in a wireless communication system analysis.

I would recommend you a book from Emil Bjrnson. He is a professor on the Linkping University and also produces a lot of content on his Youtube channel (which I will not link to avoid getting flagged as spam). His book is completely free and gives a very detailed overview:

Before giving a more detailed question below, the basic one is: can anyone recommend a good signal-processing reference which would be maximally readable by a pure mathematician (who nevertheless wants to use the techniques for actual data analysis)?

Actually, the specific thing I want to understand is how to analyze a small segment of a mystery signal, which should just be the sum of a few sinusoids, but for which the available segment is potentially much shorter than the period of the sinusoids. The goal is to recover the underlying frequencies. I'd appreciate a general reference anyway, but if someone can address my specific problem, that would help too, of course!

More detail: I am a pure mathematician, but I need to learn some signal processing techniques for a side-project in biology. At first I was excited by this, since I am already comfortable with all the "underlying" background material (essentially just Fourier transforms, etc.) and thought it would be easy enough and fun to grasp what engineers and scientists were actually doing.

However, all references I've found are written for someone with the opposite background, or at least, they are written not just to deemphasize math, but sort of to avoid it as much as possible. This makes it very hard and a bit frustrating for me to read, since firstly a bunch of terminology is thrown at me without an underlying theory (so many specific window functions with different names!) and the fact that I am very comfortable with analysis hasn't helped much. My first instinct was just to go at it alone from first principles (the definition of the DFT...) but it seems silly to ignore the vast history in this subject.

I did not mean that to sound as ranty as it did. I am not complaining, I am just wondering if anyone can recommend a reference more amenable to my background, which could take advantage of it or at least, ease me into the subject.

The book is intended for wireless signal processing, with some examples related to GSM, CDMA. It covers basic ideas: the transmission chain, fading channel; Shannon's channel's capacity theory. Advanced topics like MIMO.

A lot signal processing has uncanny resemblance to just plain Fourier analysis. Stein-Shakarchi doesn't tell you what a high-pass filter or low-pass filter is, specifically. He just figures you'll find out on your own. One cannot forget Daubechies' "Ten Lectures on Wavelets"
