LET demodulate解调函数，ZF算法，最小距离估计。-Finds minimum distance estimate of each received signal and returns the corresponding binary codeword. Use a Zero-Forcing approach for convenience

This the third post in the series discussing receiver diversity in a wireless link. Receiver diversity is a form of space diversity, where there are multiple antennas at the receiver. The presence of receiver diversity poses an interesting problem –
