This paper compares the path detection probability for Rake combining and the BER performance of packet transmission with the length of TPKT = 10(20)msec using the coherent adaptive antenna array diversity (CAAAD) receiver with those using a multi-beam receiver employing fixed antenna weights both with four antennas in a multipath fading channel in the W-CDMA reverse link. Laboratory experimental results elucidate that the required average received signal energy perbit-to-background noise spectrum density (E_b/N_o) at the detection probability of 90% of at least one path and of two paths for the fading maximum Doppler frequency of fD = 5(80)Hz using a multi-beam receiver with the number of beams equal to NBeam = 12 was decreased by approximately 1.0 (1.0)dB and 2.0 (2.0)dB, respectively, compared to that using the CAAAD receiver with the step size of μ = 10^<-2> for the average received SIR of the desired user of -12dB in a 2-path Rayleigh fading channel with average equal power in a 5-user environment. We also found that the required average received E_b/N_o at the average BER of 10^<-3> using the multi-beam receiver was decreased by approximately 5.0 (2.5)dB compared to that of the CAAAD receiver with μ = 10^<-2> and the loss of the required average received E_b/N_o compared to that of CAAAD with sufficiently converged receiver antenna weights was approximately 2.O (1.0)dB for TPKT = 10 (20) msec when the average received SIR = -12dB in a 5-user environment.
