摘要 喷泉码是一种基于删除信道的前向纠错编码技术,具有不需反馈的特性。针对深空通信环境长时延、高误码率和丢包率大、上下行链路带宽不对称和链路易中断等特点,提出一种级联LDPC码的喷泉编码方案,并给出一种利用接收数据包的冗余信息的改进BP解码算法。与已有的深空通信信道编码算法进行了仿真比较,显示了该级联喷泉码具有良好的纠错性能和较低的编解码复杂度。 Fountain code is forward error correction technology for erasure channels.To solve the problems of huge delay,higher BER and probability of lost packets,asymmetric up and down link-width,intermittence of links in deep space communications,we proposed LT code concatenate with LDPC code in fountain encoding,and a BP decoding enhancement algorithm using redundancies in the already received encoding symbols to improve the probability of performance of LT decoding presented.Compared with tradition deep space channel coding scheme,the simulation shows that the concatenated fountain code scheme has better error correcting performance and can be implemented with very low complexity to encode and decode.
