A Novel Beam-forming Algorithm in Antenna Array MC-CDMA System
Hongliang Fu, Feng Guang-zeng · 2006
A novel beam-forming algorithm in antenna array MC-CDMA system is proposed in this paper. First, the beam-formed signals on every sub-carrier are combined by using ORC, EGC or MRC, and then the decision of the combined signal and the estimated channel parameters are used to reconstruct the signal on every sub-carrier, finally the difference between the reconstructed signal and the output signal of the beam-former is used to control the coefficients of the beam-former. The bit error probability of the proposed algorithm is also analyzed in this paper
