Symbol error rate SER of quadrature subbranch hybrid selection maximal-ratio combining HS MRC scheme for 1-D modulations in Rayleigh fading under employment of the generalized receiver GR which is constructed based on the generalized approach to signal processing GASP in noise is investigated. N diversity input branches are split into 2N inphase and quadrature subbranches. M-ary pulse amplitude modulation including coherent binary phase-shift keying BPSK with quadrature subbranch HS MRC is investigated. GR SER performance for quadrature HS MRC and HS MRC schemes is investigated and compared with the conventional HS MRC receiver. Comparison shows that the GR with quadrature subbranch HS MRC and HS MRC schemes outperforms the traditional HS MRC receiver. Procedure of partial cancellation factor PCF selection for the first stage of hard-decision partial parallel interference cancellation PPIC using GR employed by direct-sequence code-division multiple access DS-CDMA systems under multipath fading channel in the case of periodic code scenario is proposed. Optimal PCF range
