A Decision-Feedback LSCM Beam-Forming Algorithm Based on Pre-despreading
Hongliang Fu, Feng Guang-zeng · 2006
A new least squares constant modulus beam-forming algorithm based on decision-feedback using pre-despreading signals(D-LSCMAFB) in DS-CDMA system is proposed in this paper.This algorithm is simulated and compared with SDCMA and DRLSCMA in additive white Gaussian channel and multipath fading channel environments.Simulation results show that the proposed D-LSCMAFB algorithm is superior to SDCMA and DRLSCMA.
