Performance Analysis of Multiantenna WiMAX Systems Over Frequency-Selective Fading Channels
Overview A multicell WiMax system which supports Orthogonal Frequency Division Multiplexing (OFDM) and antenna arrays at the base stations is considered in this paper as conforming to the IEEE 802.16-2004 standard. Focusing on the uplink, the paper proposes an analytical framework to assess the average error probability of the system over time-dispersive (or, equivalently, frequency selective) and space-dispersive (due to the antenna array) Rayleigh fading channels. The proposed method takes into account the effects of the correlation of the channel gains over the space-frequency domain, the power-angle structure of the inter-cell interference, the array processing at the base station and the interleaving scheme. Simulation results corroborate the proposed analysis for a IEEE 802.16-2004 cellular system over different propagation scenarios.
