The Symbol-Error Rate (SER) of a quadrature subbranch hybrid selection/maximal-ratio combining scheme for 1-D modulations in Rayleigh fading under employment of the Generalized Detector (GD), which is constructed based on the generalized approach to signal processing in noise, is investigated. At the GD, N diversity branches are split into 2N in-phase and quadrature subbranches. Traditional hybrid selection/maximal-ratio combining is then applied over 2N subbranches. M-ary pulse amplitude modulation, including coherent Bi-nary Phase-Shift Keying (BPSK), with quadrature subbranch hybrid selection/maximal-ratio combining is investigated. The SER performance of the GD under quadrature subbranch hybrid selection/maximal-ratio combining and hybrid selection/maximal-ratio combining schemes are investigated and compared with the conventional hybrid selection/maximal-ratio combining receivers.
