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
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!
