Maximum Ratio Combining (MRC): Getting the Absolute Most from Your Antennas
MRC weights each diversity branch by its channel gain to maximize post-combiner SNR — formula, intuition, and comparison to selection combining.

Selection combining diversity — pick the strongest branch (Matlab intuition)
Selection combining: choose the receive branch with highest SNR each fade, BER improvement vs single-antenna Rayleigh, and when SC is enough vs MRC.
