Optimal Relay Location for Fading Relay Channels
Rui Yin, Yu Zhang, Jietao Zhang, Guanding Yu, Zhaoyang Zhang, Halim Yanıkömeroğlu · 2010
In this paper we study the problem of relay-enhanced cell (REC) coverage for which relay location is optimized to maximize the achievable REC radius. The problem is investigated for both Rayleigh and Rician relay fading channels, under a pre-determined user's outage probability constraint. We propose a statistical approach to formulate the problem and develop an optimization algorithm for it. The analytical derivation is justified by numerical simulations.
