Capacity analysis in M-WiMAX uplink considering the effect of adjacent channel interference from WCDMA downlink

In this paper, we analyze the M-WiMAX UL capacity limits under 2-tier cell layout, considering the effects of random user position, path loss models, fading channel and adjacent channel interference from WCDMA downlink. To account for the requirement of the system packet error rate and the supported MCS (modulation and coding scheme) levels, we propose a MCS-based capacity analysis method, which is verified through system-level Monte-Carlo simulation. Furthermore, a comparison between the conventional Shannon method and the proposed MCS-based method is presented.
