摘要

索引调制光OFDM虽可实现高频谱效率，但其误码性能还不够理想。为此，本文结合非对称限幅光OFDM技术，通过每组激活数目不等的子载波，提出了一种广义索引调制非对称限幅光OFDM（Asymmetrically Clipped Optical OFDM with Generalized Index Modulation， ACO-OFDM-GIM）方案。每个子载波块中选择激活数目不唯一的子载波，同时引入子载波分配算法进一步提升了系统的误码性能。文中详细介绍了ACO-OFDM-GIM调制映射原理，推导了其在湍流信道下的理论误码率，并采用仿真实验进一步验证了其性能。结果表明，与ACO-OFDM、ACO-OFDM-IM等系统对比，ACO-OFDM-GIM系统的传输速率和误码性能都有明显改善。在频谱效率相同的情况下，ACO-OFDM-GIM系统在大信噪比时能够获得比ACO -OFDM和ACO-OFDM-IM系统更好的误码性能。当误码率为

Abstract

Optical orthogonal frequency division multiplexing （OFDM） with index modulation has the advantage of high spectral efficiency （SE）； however， the error performance is not optimal. In this paper， a scheme of asymmetrically clipped optical OFDM with generalized index modulation （ACO-OFDM-GIM） is proposed. In this scheme， the number of active subcarriers in each sub-block can be one or more， and these subcarriers extend the frequency domain modulation. Furthermore， a subcarrier allocation algorithm is adopted to eliminate the correlation between adjacent subcarriers. In this way， a better error performance may be achieved. Taking asymmetrically clipped O-OFDM-GIM （ACO-OFDM-GIM） as an example， the modulation mapping principle of O-OFDM-GIM has been introduced in detail. In addition， the asymptotic bit error probability of the ACO-OFDM-GIM scheme for the turbulence channel is derived and the correctness is verified via simulation. Furthermore， the performance of the ACO-OFDM-GIM system is compared with that of ACO-OFDM and ACO-OFDM-IM systems. The results showed that the transmission rate and the error performance of the ACO-OFDM-GIM scheme are improve

d compared with the ACO-OFDM-IM and ACO-OFDM schemes. When the SE is indifferent， the error performance of the proposed scheme is greater than ACO-OFDM and ACO-OFDM-IM systems at a large signal noise ratio （SNR）. When the bit error rate is 1×10

， the SNR of （4，［1，2］） ACO-OFDM-GIM scheme outperforms that of （4，2） ACO-OFDM-IM and ACO-OFDM schemes nearly 2.5 dB and 4.5 dB， under a strong turbulence channel， respectively. Therefore， the ACO-OFDM-GIM scheme is expected to effectively improve the transmission rate of atmospheric laser communication in the future.
