Abstract

A method is developed for estimating the impacts of uplink co-channel interference (CCI) on coverage in an IEEE 802.16m system. The method is based on the signal-to-interference-plus-noise ratio (SINR) requirement, which requires each mobile user to transmit enough power to satisfy a minimum SINR. The effects of shadow fading and user random locations are taken into account for the calculations of average interference power. In addition, the iterative effect of interference under power control mechanism is derived. The simulation results indicate that CCI can cause significant reduction in cell coverage, particularly when mobile users use a large amount of subchannels for high-speed data transmissions.
