为提高卫星导航系统中电文BC H码判决译码增益，利用BC H码的结构性质，设计一种低复杂度软信息译码方案。通过算法级仿真计算，兼顾性能与运算量，选择一套适用于卫星导航系统信息软译码的参数，进行硬件实现。实际验证结果表明，该方案的硬件规模变大，但在可接受范围之内，软信息译码在增加较少复杂度的情况下，译码性能获得了较大提升。

To improve the gain of decoding BCH code message in satellite navigation system ,using structural properties of BCH codes ,a low complexity decoding scheme of soft information was designed .Considering the performance and computation through algorithm level simulation ,parameters that were suitable for information software decoding of satellite navigation system were chosen ,and hardware implementation was realized .The actual validation results show that the hardware scale becomes lar‐ger but in the acceptable range ,the performance of decoding soft information is greatly improved on the premise of increasing lit‐tle complexity .
