摘要：
Aimed at the emerging massive multiple-input multiple-output (MIMO) systems, both hard-decision and soft-decision detectors are investigated for the generalized space shift keying (GSSK) modulation scheme, where a codebook-assisted technique is used to reduce the tree-search complexity. Furthermore, the outer low-density parity-check (LDPC) code is optimized such that the proposed system design can provide an error performance, which is almost the same as that of the scheme that uses the maximum a posteriori (MAP) soft detector, but with a much lower computational complexity.
