abstract: This paper presents the performance evaluation of an amplify-and-forward(AF) relay-assisted multiuser multiple input–multiple output (MU–MIMO)downlink transmission system for correlated fading channels. The overall sys-tem performance was improved by incorporating a double-quadrature spatialmodulation (DQSM) scheme. The bit error rate (BER) performance and detec-tion complexity of the AF–MU–MIMO–DQSM system were analyzed and com-pared with those of a conventional AF–MU–MIMO system under the sameconditions and parameters. The results showed that the correlated fadingchannel severely affected the performance of systems with higher spectral effi-ciency (SE). Considering an SE of 12 bpcu/user, the AF–MU–MIMO–DQSMsystem yielded a gain of up to 3 dB in BER performance compared with that ofits conventional counterpart for the analyzed cases. In terms of detection com-plexity, the AF–MU–MIMO–DQSM system showed a reduction of up to 56 %25compared with that of the conventional system for the optimal maximum like-lihood detection criterion.
