In this paper, an efficient Decode-and-Forward (DF) relay selection scheme for interference-limited relaying networks is considered. In contrast to previously reported works, we consider multiple interferences which make the conventional relay selection schemes not suitable for interference-limited networks and propose a new relay selection scheme for DF protocol with multiple interferences. Approximate...
In this paper, we investigate the outage performance of decode-and-forward (DF) based opportunistic cooperative communications with channel estimation errors at the receivers under Rayleigh fading channels, in which the effect of the direct link has been explicitly evaluated. To be specific, the exact expression of outage probability has been derived for arbitrary values of signal-to-noise ratio (SNR)...
In this paper, we analyze the ergodic capacity (per unit bandwidth) and Average symbol error probability (ASEP) of an incremental relaying protocol used in conjunction with opportunistic relaying and consider a non-regenerative wireless relay network with Rayleigh fading channels. We consider a selection combining technique at the destination in order to combine the two signals, one from the direct...
In this letter, we study outage performance of opportunistic single relay selection (OSRS) in decode-and-forward (DF) relaying with unequal-power co-channel interferers under Rayleigh fading channels. With the interferers, signal-to-interference-plus-noise ratio (SINR) may not be so great when the interferers also transmit signals at a power level similar to the source. In this case, high signal-to-noise...
