ABSTRACT:
Disclosed herein is a method for eliminating the reception interference signal of a Space-Time Block Coded Orthogonal Frequency-Division Multiplexing (STBC-OFDM) system in a high-speed mobile channel. The method includes the following steps. At the first step, the gain of a channel combined at a receiving end is estimated in the case of using the STBC-OFDM system on a time-varying channel. At the second step, first temporary decision symbols are obtained by performing comparison on the estimated gain. At the third step, second temporary decision symbols are obtained using the first temporary decision symbols. At the fourth step, self-channel interference (SCI) terms are eliminated using the second temporary decision symbols and third temporary decision symbols are obtained. At the fifth step, final data symbols are obtained using the third temporary decision symbols.
