Sub-carrier Resource Management for OFSDMA System Using RoF Ubiquitous Antennas

摘要

In this paper, we propose a new resource management scheme for multiple data streams in an orthogonal frequency and space division multiplex access (OFSDMA) system using Radio-On-Fiber (RoF) ubiquitous antennas. The proposed scheme classifies the service classes into some classes in which the number of sub-carriers is dynamically changed according to the required data rate. The computer simulation results show that the proposed scheme improves the number of users satisfying the required bit error rate (BER) level as well as the average throughput.
