摘　　要：面向无线体域网(WBAN)传输环境,该文主要论述信道编码与联合信源信道编码系统的码字设计。针对物理层的低功耗和高可靠传输需求,从低密度奇偶校验(LDPC)码的优化设计角度展开,主要在信道模型分类、传输系统构建、技术挑战与解决方案、信道适配性编码设计这4个层面进行梳理和总结。最后,对WBAN环境下LDPC码优化设计的未来研究工作进行展望,为构建下一代通信技术提供参考。In this paper,the code designs based on the channel coding and the joint source channel coding systems are surveyed over the transmission environment of the Wireless Body Area Network(WBAN).For the requirements of low-power consumption and high reliability on the physical layer,the perspective of optimal design based on the Low-Density Parity-Check(LDPC)code is investigated.Four aspects are summarized,including the classification of channel models,the construction of transmission system,the technical challenges and solutions,and the coding design with channel adaptability.Finally,some future works are prospected for optimally designing the LDPC codes over the WBAN environment,which will provide some references to construct the next-generation communication technology.
