  • In this paper, a iterative receiver is introduced for convolutionally coded distributed MIMO with V-BLAST architecture. A maximum-likelihood (ML) iterative detector and a low-complexity Turbo detection scheme are proposed. The computational complexity is O(2MTSlogM) and O(M2TM2RS2M) respectively. Simulation results in quasi-stationary, single-path Rayleigh fading channel demonstrate that the proposed low-complexity iterative detection algorithm offers significant performance improvement about 7.5dB at than the non-iterative zero-forcing detection. At same BER (Bit Error Rate), 1 iterations Eb/N0 is 3dB above 6 iterations. Performance improvement gradually declines as the number of iteration increases.
