MULTI-USERS DETECTING METHOD AND DEVICE OF OFDM TRANSMISSION SIGNAL

摘要

Multi-users detecting method and device of OFDM transmission signal include that: a received data sequence is composed of the received signal which is in the position of the time and frequency symbol corresponding to the same data symbol in multi -repeating blocks; the composed repeating channel response sequence array which is corresponding to the received data sequence is determined; the received data sequence is detected to acquire the data symbol information of multi-users by using the composed repeating channel response sequence array. The technical solution can effectively restrain the multi-address interference and the interference between symbols during OFDM transmitting signal and improve the system performance greatly.
