Abstract

This paper investigates the problem of MAI (Multiple Access Interference) occurrence when timing misalignment occurs in the downlink channel of OFDM-based networks. The adaptive guard band allocation scheme is mainly designed to achieve timing synchronization while reducing guard carrier redundancy and maintaining high channel throughput in asynchronous OFDM-based networks. Thus, the proposed scheme reduces the effect of MAI for users receiving multiple transmission signals from surrounding BSs (Base Stations). In a simulation, it is noteworthy that this adaptive carrier allocation is very effective in reducing MAI for asynchronous multi-cell network.
