Optimal RS Location And Bandwidth Allocation For Relay System With Decode-Amplify-Forward Scheme
In this paper, the optimal relay station (RS) location and the bandwidth allocation for RS in fixed RS based radio cooperation system are investigated to maximize the data rate when the RS adopts decode-amplify-forward (DAF) scheme. According to the information-theoretic achievable rate maximization policy, the MS selectively accesses base station (BS) or RS, and the optimal RS location is obtained to maximize the system capacity for relaying system with three sectors within which there is one fixed RS. And then the optimal bandwidth allocation for the RS is gotten by calculating the percentage of MS which accesses RS. Numerical simulation is implemented to find the optimal RS location and bandwidth allocation for RS in IEEE 802.16j based relay system.
