摘要 为了提高室内可见光通信(VLC)系统性能并充分利用信道带宽资源,将OFDM与自适应技术结合应用于VLC系统中。讨论了系统反馈途径的实现方法,在室内空间环境建模的基础上,对自适应OFDM通信系统的吞吐量和误码率进行了Matlab仿真和分析。 The paper combines orthogonal frequency division multiplexing(OFDM) modulation with adaptive tehconlogy used in the indoor visible light communication (VLC) system in order to improve the VLC system performance and makes full use of the bandwidth resource of channel. It discusses the realizing method of system feedback method, simulates and analyzes between the throughput of the adaptive OFDM communication system and bit error rate(BER) by using Matlab software on the basis of the indoor space environment modeling.
