ABSTRACT In this paper, the performance of a dual-hop Amplify-and-Forward (AF) multi-antenna relay network, with end-to-end (e2e) best antenna selection, is investigated. To investigate the performance of this system, we first derive the exact outage probability in closed-form. It is then used to obtain expressions for e2e SNR moments and the average symbol/bit error rate (SER/BER) valid for a large class of practical modulation schemes. A simple and accurate BER approximation is also derived to quantify the performance at high SNR. Our analytical results, show that the e2e antenna pair selection scheme achieves the same diversity order as for the case where all antennas are used. To further confirm the validity of our analysis, Monte Carlo simulation results are also presented.

    ABSTRACT: In this paper, the performance of a two-way amplify and forward (AF) multi-antenna relay network is presented, where the worse receive signal-to-noise ratio (SNR) of the two end users is maximized. We first derive the exact probability density function (PDF) of receive SNR for two users. Then an approximate expression of SNR in the high-SNR regime is obtained. A closed-form average sum bit error rate (BER) approximation is also derived to quantify the performance of the antenna selection system at high SNR. It is shown by simulation that our analytical result is efficient in estimating the network reliability, especially in the high transmit SNR region.

    ABSTRACT: In this paper, we analyze the performance of two sub-optimal antenna selection strategies for single relay based selective decode-and-forward (DF) cooperative multiple-input multiple-output (MIMO) systems. We assume that the source-relay, relay-destination, and the source-destination channels follow the Rayleigh fading. We derive the closed-form expressions and the upper bounds of the symbol error rate (SER) for selective DF cooperative MIMO systems employing M-ary phase shift keying in both the antenna selection strategies. From the derived SER upper bounds, we extract the diversity orders of the system in both the selection strategies. The optimal power allocation for the source and relay is derived in both the selection strategies, which minimize the SER of DF cooperative MIMO system.

    ABSTRACT: In this paper, the performance of the dual-hop Multiple-input multiple-output (MIMO) amplify-and-forward (AF) relay systems with transmit beamforming and maximum ratio combining scheme (MIMO-MRC) is investigated over interference-limited Rayleigh fading channels. Exact closed-form expressions have been derived for the cumulative distribution function (CDF) and probability distribution function (PDF) of the equivalent signal-to-interference-plus-noise ratio (SINR), the outage probability, and average symbol error rate (SER). Finally, numerical results and Monte Carlo simulations are carried out, by which we verify the validity of our analysis and study the effects of various parameters on the system performance.
