Abstract

A two-phased approach is proposed to estimate the overall multi-hop WiMax system performance. The proposed methodology is generic and can embrace various multi transmit multi receive techniques along with different possible (H)ARQ mechanisms. Advanced modulation and coding sub-carrier mapping is assumed for static and low mobility links to allow operation of adaptive techniques such as dynamic band allocation and beam-forming. PUSC sub-carrier mapping is assumed to be used for dynamic and high mobility links. In order to illustrate our methodology, the overall PER performance of a two-hop system with eigen beamforming in first hop and either Alamouti or Golden codes in the second hop has been estimated. The results are based on the combination of the two link performance models, i.e., actual value interface for the first hop and average value interface for the second hop.
