Abstract | In this paper, a cooperative communication scheme with inter-relay interference (IRI) cancellation is proposed for wireless multi-user multi-decode-and-forward (DF) relay networks. The scheme is based on a DF half-duplex (HD) relaying protocol and a relay selection method which maximizes the signal-to-noise ratio (SNR) of the second hop. To enhance the spectral efficiency and cancel the IRI, the proposed scheme (constellation real part (CRP)) uses a new virtual full-duplex relaying protocol based on the constellation real parts of the modulated signals and the two-path successive relay scheme. To assess the performance, we derive the expressions of the outage probability, and the average bit error rate (BER) for the CRP scheme. Simulations are used to validate the analytical expressions. The results confirm the advantage of the proposed scheme in enhancing the performance of wireless cooperative networks. |
