可见光通信(VLC)可实现高速无线通信,同时满足室内环境的照明要求。在本文中,我们研究了多次反射条件下 VLC 系统的性能。我们通过使用正交频分复用 (OFDM) 最大限度地减少码间干扰 (ISI) 的影响。特别地,在OFDM中使用保护间隔(GI)来减轻码间干扰。我们使用 MATLAB 进行仿真来演示我们提出的 VLC 系统的性能。仿真结果表明,保护间隔的使用显着降低了 ISI,从而提高了误码率 (BER) 性能。
Visible light communication (VLC) enables high speed wireless communication along with fulfilling the illumination requirement in the indoor environment. In this paper, we investigate the performance of a VLC system under multiple reflection condition. We minimize the effect of intersymbol interference (ISI) by using orthogonal frequency division multiplexing (OFDM). Particularly the use of guard interval (GI) in OFDM is utilized to mitigate intersymbol interference. We performed simulation using MATLAB to demonstrate the performance of our proposed VLC system. Simulation results show that the use of guard interval significantly reduces the ISI and hence improves bit error rate (BER) performance.
