mimo-ofdm 不同信道估计的对比 ls lmmse dft-Mimo ofdm different channel estimation contrast

OFDM中LS和DFT信道估计算法matlab程序实现及比较-OFDM, DFT LS and channel estimation algorithm matlab program to achieve and compare

ofdm信道估计，用ls和dft的不同的方法进行了比较，有ber曲线-ofd channel estimation

通过LS和DFT方法对OFDM实现了信道估计，并对估计后的信道同原始信道进行对比，还有不同信噪比下的误码仿真-Through LS and DFT method to achieve the OFDM channel estimation, and the estimated channel compared with the original channel, as well as the BER simulation under different signal to noise ratio
