Joint User and Antenna Selection for Multiple-antenna Wireless Relay Networks

  • Author(s) / Creator(s)
  • Multiple-antenna technology and relaying techniques are integral components of next generation wireless standards such as Long-Term Evolution-Advanced (LTE-A) and Worldwide Interoperability for Microwave Access (WiMAX). In this project, joint antenna and source selection strategies are designed and analyzed for multiple-antenna amplify-and-forward relay networks. To this end, the optimal transmit antenna pair at the best source and the optimal transmit-receive antenna pair at the relay are selected to minimize the overall outage probability of the multi-user multi-antenna relay networks. Under the aforementioned strategy, the end-to-end transmission scheme is first formulated and thereby the underlying transmission schemes are analyzed to obtain system specific performance metrics. To this end, the important performance metrics including the outage probability and average bit error rate are derived in closed-form. To obtain useful insights into practical system designs, numerical results pertinent to various system configurations are presented by using Matlab simulations. Here, the analytical lower bounds for the outage probability and average bit error rates are plotted by using the closed-form derivations while the corresponding exact performance metrics are plotted by using Monte-Carlo simulations. Valuable insights and intuitions, which are useful in designing practical multi-antenna relay networks, are then drawn by using these simulations results. (As cited in abstract.)
