摘要：
A novel blind widely linear (WL) minimum output energy (MOE) algorithm is proposed for the CDMA receiver, Whereas the conventional WL algorithms are only applicable to real-valued modulation, the proposed receiver is applicable to complex-valued modulation. The blind WL-MOE filter is analyzed, and the convergence properties of an adaptive implementation are derived. Simulation results confirm that the proposed algorithm has higher steady-state SINR and faster convergence speed than the conventional MOE algorithm but cannot outperform the conventional WL-MOE due to severer constraints.
