论文摘要
在此通信中，我们提出了一个用于与光学无线系统合并光学正交频部多路复用（O-OFDM）和索引调制（O-OFDM-IM）的框架。这两种方案都具有某些局限性，例如O-OFDM不提供光谱效率（SE）/能源效率（EE）权衡的任何粒度，而O-OFDM-IM对于高阶调制字母损失了EE。通过将O-OFDM和O-OFDM-IM组合在一起，可以规避上述限制。在提供一般框架之后，我们使用不对称的剪辑（AC）O-OFDM和ACO-OFDM-IM来证明框架的有效性。本文提出的结果表明，除了提供SE/EE权衡外，通过合并O-OFDM和OFDM-IM，我们还可以在高SE的EE方面认识到更高的SE和跑赢方面的O-OFDM-IM。
In this communication, we propose a framework for amalgamating optical-orthogonal frequency-division multiplexing (O-OFDM) and O-OFDM with index modulation (O-OFDM-IM) for optical wireless systems. Both schemes individually have some limitations, e.g., O-OFDM does not provide any granularity for spectral efficiency (SE)/energy efficiency (EE) trade-off, and O-OFDM-IM loses EE for higher order modulation alphabets. By combining O-OFDM and O-OFDM-IM together, the above limitations can be circumvented. Following on from providing the general framework, we use asymmetrically clipped (AC)O-OFDM and ACO-OFDM-IM to demonstrate the validity of the framework. The results presented herein establish that, by consolidating O-OFDM and O-OFDM-IM, in addition to providing SE/EE trade-off, we may realise higher SE and outperform O-OFDM-IM in terms of EE for high SE.
