| Abstract(in English) | This paper proposes a method for generating the likelihood function of complexity-reduced maximum likelihood detection (MLD) based on symbol replica-candidate selection with QR Decomposition suitable to soft-decision Turbo decoding for Orthogonal Frequency and Code Division Multiplexing (OFCDM) multiple-input multiple-output (MIMO) multiplexing. The simulation results show that the proposed method in 4-by-4 MIMO multiplexing significantly reduces the required average received signal energy per bit-to-noise power spectrum density ratio (E_b/N_0) at the average block error rate of 10^<-2> at the data rate of 1 Gbps compared to that using hard-decision decoding in OFCDM access with 16 QAM modulation, the coding rate of 8/9, and eight-code multiplexing for the spreading factor of eight assuming a 100-MHz bandwidth. |
