Ordered Successive Interference Cancellation Mimo Decision Feedback Equalization Based on Constant Modulus Property

The ordered successive interference cancellation MIMO decision feedback equalization based on constant modulus property is obtained by canceling decided symbols from the received symbols successively with the decision feed-forward equalizer (DFE) solution as a well known expression encountered in improved log-normal error function based on CMA (ILNCMA-OSIC-DFE) adaptive algorithms. The decision feedback equalizer replaces a convolution of the decision feed-forward equalizer with the channel. The ILNCMA-OSICDFE algorithm avoids the interference of the decided symbols and improves the detection performance. In the environment where lots of wireless communications are scattered over, simulation testing and the results shown that the detection performance of proposed algorithm is dramatically improved in comparison with the traditional ordered decision feedback equalization based on recursive least square algorithm (RLS-O-DFE).
