For a SIMO system, when all sub-channels have no non-zero common zeros and channel input signals have zero mean and are temporally uncorrelated, the sufficient and essential condition of equalizing channel is that equalizer output signals are also temporally uncorrelated. Based on this theory, this paper proposes a new equalization algorithm. The proposed algorithm estimates directly equalizer without knowing the channel impulse response. The proposed algorithm is based on equalizer output temporally uncorrelated characteristic and second-order statistics of the received signals. A 16QAM complex SIMO multipath channel system is simulated with the proposed algorithm in this paper. Simulation results show that the proposed algorithm has a good equalization performance.
