    Abstract

    In this paper, we generalize the iterative algorithms proposed in [6] to amplify-and-forward multiuser multiple-input multiple-output (MIMO) relay communication systems with the source-destination links. Compared with [6], where the source-destination links are ignored, the evolved Tri-Step method and Bi-Step method are derived for the new system model with the source-destination links for more spatial diversity gain. From the theoretical derivation of the minimum mean-squared error (MMSE) of the signal waveform estimation at the destination node, we show that the existence of the source-destination links bring benefits no matter how weak they are. Numerical examples demonstrate that the evolved algorithms perform much better than the original algorithms in [6] and other existing ones in terms of both MSE and bit-error-rate (BER).
