Conference Paper: Outage probability and SER of twohop MIMO relaying systems with a fixedgain relay and antenna selection
[Show abstract] [Hide abstract]
ABSTRACT: A twohop amplifyandforward (AF) multipleinput and multipleoutput (MIMO) relaying system with antenna selection at each node is analyzed in this paper. Fixedgain relaying strategy which has a low complexity is considered at the relay. New exact expressions for outage probability and average symbol error rate (SER) for a variety of modulation schemes are derived. To gain insight as to how parameters influence system performance, the coding gain and diversity diversity are analytically presented. Also, asymptotic behavior for outage probability and average SER at high signaltonoiseratio (SNR) are quantified. Finally, computer simulations are compared with the analytical expressions to verify the exactness of the derived theoretical results.Communications and Networking in China (CHINACOM), 2012 7th International ICST Conference on; 01/2012 
Conference Paper: Performance analysis of dualhop MIMOMRC AF relaying in the presence of cochannel interference at the destination
[Show abstract] [Hide abstract]
ABSTRACT: In this paper, the performance of the dualhop Multipleinput multipleoutput (MIMO) amplifyandforward (AF) relay systems with transmit beamforming and maximum ratio combining scheme (MIMOMRC) is investigated over interferencelimited Rayleigh fading channels. Exact closedform expressions have been derived for the cumulative distribution function (CDF) and probability distribution function (PDF) of the equivalent signaltointerferenceplusnoise 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.Wireless Communications & Signal Processing (WCSP), 2012 International Conference on; 01/2012  [Show abstract] [Hide abstract]
ABSTRACT: We consider an endtoend antenna selection (E2EAS) scheme for a multipleinput multipleoutput (MIMO) twoway relaying system with amplifyandforward (AF) based relay terminal between two source terminals, each having multiple antennas. The proposed E2EAS strategy involves selecting a single best antenna at each terminal of the system. Under a Rayleigh flatfading environment, we present exact and asymptotic expressions of the overall system outage probability. We show that with singleantenna selection at each terminal, the underlying strategy achieves the same diversity order as the scheme using all the available antennas. We also highlight the impact of relay location and power allocation on the overall system outage performance. Finally, we provide numerical and simulation results to confirm the theoretical analysis and the performance of the proposed scheme.Sarnoff Symposium (SARNOFF), 2012 35th IEEE; 01/2012
