本文提出的仿真结果展示了在带限可见光通信 (VLC) 系统中通过判决反馈均衡器 (DFE) 增强实现多频段无载波幅度和相位 (m-CAP) 调制的原理。当部署不同数量的子载波 m = {1, 2, 5, 10} 时,我们展示了在使用和不使用 DFE 的情况下 m-CAP 在 1 Hz 固定系统带宽上的误码率 (BER) 性能。我们表明,当 m = {1, 2} 时,m-CAP 系统可以实现 10-4 的 BER,这分别远低于 7% 和 20% 前向纠错 (FEC) BER 限制 3.8×10-3 和 2×10-2。
This paper presents simulation results that show the principle of implementing multi-band carrierless amplitude and phase (m-CAP) modulation enhanced by the decision feedback equalizer (DFE) for a bandlimited visible light communications (VLC) system. When deploying different number of sub-carriers m = {1, 2, 5, 10}, we show the bit error rate (BER) performance of m-CAP over a fixed system bandwidth of 1 Hz with and without a DFE. We show that we can achieve a BER of 10-4 for the m-CAP system for m = {1, 2}, which is well below the 7% and 20% forward error correction (FEC) BER limits of 3.8×10-3 and 2×10-2, respectively.
