Title
Ranging improvement using Successive Interference Cancellation for multiuser M-WiMAX system
Abstract
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 propose a ranging algorithm, applying SIC (Successive Interference Cancellation) to the conventional ranging algorithm, for the MAI minimization and ranging performance improvement. The proposed ranging algorithm is verified through a Monte Carlo simulation, which shows the enhanced performance of ranging code detection and delay time estimation compared to the conventional algorithms.
