A Novel Distributed VBLAST Adaptive DFE Algorithm in Cooperative MIMO

This paper proposes a method of LDPC coded combined with space-time codes using in the cooperative MIMO system. An algorithm is introduced that the joint iterative detection algorithm based on Fincke-pohst (sphere detecting) maximum a-posteriori (MAP). theoretical analysis and derivation shown that the performance of LDPC cascading space-time codes (STBC) system is slightly better than that of LDPC coded cascading vertical layered space-time codes (VBLAST) in cooperative MIMO systems. And the FP-MAP detection algorithm compares with the detection algorithm-zero forcing sort plus interference cancellation(ZF-OSIC) and the recursive least squares decision feedback equalization(RLS-DFE) algorithm, its performance is improved by about 0. 6dB and 0. 3dB respectively, its performance is closest to the ML detection.
