In the uplink of OFDMA (Orthogonal Frequency Division Multiple Access) based M-WiMAX (Mobile-Worldwide Interoperability for Microwave Access) system, linear phase shift is caused by signals transmitted from multiuser with different delay time and thus, MAI (Multiple Access Interference) occurs. MAI degrades the performance of ranging code detection and delay time estimation in the uplink. Therefore,...
In this paper, we develop a novel analytical model to examine the coverage and capacity of MBSFN (MBMS over a single frequency network) OFDMA, proposed to deliver TV services to mobile users in forthcoming 3G LTE networks. First, analytical expression for SINR at a given point in a cell is derived, which takes into account the SFN gain and propagation delay values. Next, the shadowing effect of propagation...
