用于高频谱效率VLC系统的非正交多频带CAP
Non-Orthogonal Multi-band CAP for Highly Spectrally Efficient VLC Systems
摘要：
在这项工作中，我们提出并实验证明了一种新的非正交多带无载波幅度和相位（NM-CAP）的方案，用于带限可见光通信系统，以提高频谱效率。我们表明，节省高达30%的带宽可以实现，从而导致44%的改善，在测量的频谱效率没有进一步的误比特率性能下降相比，传统的m-CAP计划。我们还表明，高阶系统可以提供更高的带宽压缩比低阶系统。此外，在发射机或接收机处没有附加的功能块的情况下，所提出的方案不引入额外的计算复杂度。
英文摘要：
In this work we propose and experimentally demonstrate a novel non-orthogonal multi-band carrier-less amplitude and phase (NM-CAP) scheme for bandlimited visible light communication systems in order to increase the spectral efficiency. We show that a bandwidth saving up to 30% can be achieved thus resulting in 44% improvement in the measured spectral efficiency with no further bit error rate performance degradation compared to the traditional m-CAP scheme. We also show that higher order systems can provide higher bandwidth compression than low order systems. Furthermore, with no additional functional blocks at the transmitter or the receiver the proposed scheme introduces no extra computational complexity.
