摘要:

无线光通信的信道环境复杂,易受雨、雪、雾等自然现象的影响,通常采用信道编码的方式纠正信道噪声引起的误码,信道编码有里德-所罗门(RS, Reed-Solomon)码、Turbo码、低密度奇偶校验(LDPC, low density parity check)码和极化码等多种类型。梳理了纠错码的发展脉络,总结了纠错码用于无线光通信的研究进展并进行对比分析,在此基础上介绍了西安理工大学在该领域的理论和实验研究进展,比较分析了 RS 码、Turbo 码、LDPC码在雨、雪、雾环境下的纠错特性。最后,指出了该领域未来可能的研究方向和挑战,为相关领域未来的发展和研究提供参考。

Abstract:

The channel environment of the optical wireless communication is complicated, susceptible to various natural phenomena such as rain, snow, and fog.The channel code is usually used to correct the error caused by the channel noise.Common channel codes are Reed-Solomon (RS) code, Turbo code, low density parity check (LDPC) code, polarization code and other types.The development of the error correction code was combed, the research progress of the error correction code for the optical wireless communication were summarized and the comparative analysis was made, which introduced the progress of Xi'an University of Technology in this field of theory and experimentation.RS code, Turbo code, LDPC code were comparable to the error correction characteristics in rain, snow and fog environments.Finally, the future possible research direction and challenges were pointed out, providing references for the future development and research in the relevant fields.

Key words: optical wireless communication, error correction coding, bit error rate
