Research on Adaptive Resource Allocation of Indoor MIMO-OFDM Visible Light Communication System

Abstract

In this paper, the performance of three typical resource allocation schemes is analyzed, which are applied to indoor MIMO-OFDM visible-light communication system, the maximum capacity allocation algorithm, the rate proportional algorithm and the multi-user subcarrier ordering allocation algorithm. The result of simulation shows that the three algorithms above can effectively improve the performance of indoor MIMO-OFDM visible light communication system. The system is capacity is at least 3 times higher. Simultaneously, in the system capacity, error performance and fairness, these three allocation method are significantly different.
