Resource Allocation in Amplify-and-Forward Relay-Assisted DS/CDMA Systems
Alessio Zappone, Eduard Axel Jorswieck · IEEE Transactions on Wireless Communications · 2012
Non-cooperative resource allocation in amplify-and-forward relay-assisted DS/CDMA networks is tackled in this paper. The relay allocates its amplify-and-forward matrix for achievable sum-rate maximization, whereas the mobile transmitters selfishly allocate their spreading codes for individual achievable rate maximization. Convergence of the proposed algorithm is proved and its performance contrasted against a centralized approach. Moreover, the proposed approach is extended to the case in which the direct path between transmitters and receiver is taken into account.
