MIMO通信系统中的3大部分：空时编码、系统容量、信道估计【Matlab平台实现】

# MIMO-OFDM-Channel-Estimation Channel Estimation for MIMO OFDM Systems (LSE& MMSE)  try out `example_run.m` to start ```matlab function [h_hat,H_hat] = mimoOfdmChannelEst(rxSymbs,pilots,pilotPos,Nt,Nr,nFFT,nTaps,N0,estMethods) % estimate channels in MIMO-OFDM systems(LSE/MMSE) % rxSymbs - received symbols a nFFT X Nr vector % pilots - pilot symbols, a nP X 1 vector, nP isnumber of pilots % pilotPos - positions of pilots a nP X 1 vector, % Nt - number of transmit antennas % Nr - number of receive antennas % nFFT - fft size % nTaps - the number of taps of the channel % N0 - noise variance % estMethods: 'LSE' or 'MSE' % h_hat - estimated channel impulse response % H_hat - estimated channel frequency response` ``` [ref] I.
