English Description：
In this code, the least square error channel estimation of MIMO OFDM system is realized. In this code, the least square error channel estimation of a is considered. Users can access the design parameters of MIMO OFDM system and channel state information. The L-TAP Rayleigh fading channel is considered between any pair of transmit and receive antennas. The mean square error of LSE channel is obtained, and the simulation results are compared with the theoretical calculation results. source paper : "Optimal Training Design for MIMO OFDM Systems in Mobile Wireless Channels"
