A novel constellation mapping VBLAST zero forcing detection algorithm in MIMO-OFDM system is proposed in this paper. First, the signal is cycled and successively mapped from the whole space of constellation points and is regarded as the first the underlying detection signals to maximize the performance of the first detection layers at the receiver. Then, the traditional ZF detection algorithm is used...
In this paper, considering the error propagation effect and high complexity of spatial multiplexing based vertical bell labs layered space time(VBLAST), a novel nonlinear MMSE-THP algorithm for VBLAST in MIMO-MC-CDMA downlink system is proposed in this paper. In the proposed algorithm, the nonlinear THP precoding is used between the sub-carrier channels of the MC-CDMA to eliminate interference from...
Considering the error propagation effect and high complexity of spatial multiplexing based vertical vell labs layered space time(VBLAST), a novel nonlinear module algebra precoding algorithm based on geometric mean decomposition for VBLAST is proposed in multiple input multiple output multi-carrier code division multiple access (MIMO-MC-CDMA) downlink systems, geometric mean decomposition is used...
