A Novel Cell Architecture Based on Distributed Antennas for Mobile WiMAX Systems

A mobile WiMAX system based on IEEE 802.16e wireless metropolitan area networks targets to support mobile broadband wireless access (BWA). In this article we propose a cell architecture based on distributed antennas (DAs) for mobile WiMAX systems to improve the capacity and performance. The new architecture has some good features compared to the conventional cell splitting structure and traditional point-to-point MIMO system. Under this architecture, the system design is flexible and scalable with different performance requirements and complexity. Furthermore, different levels of implementation are given by some general introduction with a case of simulation which shows an obvious performance enhancement in outage probability.
