Notes or books to quickly get started on the basics of signal processing or wireless communication I'll soon start working in signal processing, specially wireless communication systems. Hence I'd like to get a quick understanding of MIMO and related systems, for example, the topics like:

1) where and how the model $y=Hx + n$ arise,

2) fading, Rayleigh fading,

3) channel capacity, channel state information,

4) other basics one must know

etc.

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.

An intrductory (easy to understand) material that'd help me gain all these necessary basics in a week (or say ten hours) would be greatly appreciated. Thank you in advance!
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.


Modern Wireless Communication Systems


Similar known authors do have related books, but I guess most compact academic begining would be this one.

It's not a practical book by any comparison, and therefore does not discuss any bit of a practical application of any of the mathematical analysis it intruduces...

If this book contains advanced materials then you may consider reading its pre-requisites from the same author:


Introduction to Analog and Digital Communications


Furthermore you can enhance your Matlab applications on the fundamental communication systems by the following book from the author Proakis.
