A novel blind widely linear (WL) minimum output energy (MOE) algorithm is proposed for the CDMA receiver. Whereas the recently proposed WL-MOE algorithm is only applicable to real-valued modulation, the proposed receiver is applicable to complex-valued modulation as well. The blind WLMOE filter is analyzed, and the convergence properties of an adaptive implementation are derived. The proposed algorithm dramatically outperforms non-widely linear MOE algorithms when at least one of the signals (desired or interference) is improper, i.e. real-valued.
