我们实现了一个（204，188）-Reed-Solomon码的软判决解码器，该码广泛应用于卫星、地面和其他广播系统的标准中。解码器采用了列表解码技术，使用迭代自适应置信传播和有界距离解码。通过MAP解码从列表中选择一个解码字，并应用一些想法来降低其复杂度。当信道吞吐量为32 Mbps时，该译码器在FPGA中工作在88 MHz，与普通硬判决译码器相比，获得了1 dB的性能增益。
We implemented a soft-decision decoder of (204,188)-Reed-Solomon code, which is used widely in standards for satellite, terrestrial, and other broadcasting systems. The decoder employs a list decoding technique using iterative adaptive belief propagation and bounded distance decoding. One decoded word is chosen from the list by MAP decoding, and some ideas are applied to reduce its complexity. When the channel throughput is 32 Mbps, the decoder works at 88 MHz in an FPGA, and obtains 1 dB performance gain compared with ordinary hard-decision decoders.
