Abstract
A method and device for multi-user detecting of an OFDM transmission signal are provided. The method includes: combining received signals, at corresponding time-frequency symbol positions in all of multiple repeated Block Units in relation to the same data symbol, into a received data sequence; determining a combined repeated channel response sequence array corresponding to the received data sequence; and detecting the received data sequence using the combined repeated channel response sequence array to obtain data symbols of multiple users. 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.
