In this paper, we consider a dual-hop amplify-and-forward (AF) relay system, where the base station (BS) equipped with multiple antennas communicates with the mobile station (MS) via a relay station (RS). We derive the exact closed-form outage probability for two cases: i) interference only at the MS and ii) interference at both the RS and the MS. It is validated that our analyses agree with the corresponding...
In this paper, we study the error performance of two-way amplify-and-forward (AF) relaying over independent but not necessarily identically distributed Rayleigh fading channels, in the presence of co-channel interfering signals affecting the network nodes. Closed-form expressions for the cumulative distribution function (CDF) of the signal-to-interference-plus-noise ratio (SINR) and for the error...
In this paper, the performance of opportunistic amplify-and-forward multi-hop multi-branch relaying systems operating in the presence of co-channel interferences is investigated. Considering transmissions over independent non-identical Rayleigh fading channels, exact and upper-bound expressions for the end-to-end signal-to-interference-plus-noise ratio (SINR) are obtained. Then, the cumulative distribution...
In this paper, the impact of co-channel interference on the achievable uplink spectral efficiency of an in-building wireless communication system employing DAS is examined. In the system, remote antenna units (RAUs) are deployed on each floor throughout the building and connected to a central unit (CU) where received signals are processed. System performance is investigated by using a propagation...
In this paper we analyze the effect of co-channel interference on the performance of cooperative decode-and-forward (DF) automatic-repeat-request (ARQ) scheme under Rayleigh fading channels. We assume that the relay node is affected by one interferer and the destination node is affected by another one. The outage probability of the cooperative DF ARQ scheme is derived based on the maximal ratio combining...
