Abstract

In this paper, we introduce a collaborative minimum mean squared error (MMSE) interference canceler in MIMO relay networks. The proposed receiver architecture is characterized by the integration of the generalized minimum residual method (GMRES) for symbol detection. In this scheme, the GMRES method detects the transmitted symbols by solving iteratively a linear system representing the MMSE interference canceler without matrix inversion. The relay-destination channels are assumed to be orthogonal. We evaluate the instantaneous capacity of the equivalent MIMO relay network equipped with K parallel relay nodes for TDMA and MC-CDMA modes, using the assumption that the source node does not communicate directly with the destination node. In order to evaluate the system performances, the bit error rate (BER) is evaluated with respect to the number of relay nodes K and the signal to noise ratio (SNR) measured at the destination.
