MIMO Signal Processing - Part I — Lesson 1

This lesson covers concept of the classical IID channel, spatial fading correlation, and the impact of correlated channel coefficients. The lesson introduces the concept of moment generating function. It further explains the concept of general diversity and how it can be used to maximize the received signal-to-noise ratio (SNR). This lesson also explains the Average probability of error. The lesson concludes with the receive diversity concept.
