OFDM信道估计(梳状导频)，差分检测对比仿真。 非常简单，清晰明了，适合OFDM初学者-OFDM channel estimation (pilot comb), differential detection simulation comparison. Very simple, clear, suitable for beginners OFDM

this matlab code about testing ofdm

本程序给出了OFDM信道的仿真，直接运行主函数OFDM_test即可，给出了信道BER随SNR的关系。-This procedure gives a simulation of OFDM channel and run directly the main function OFDM_test can, given the relationship between the channel BER with SNR.
