摘　　要：在简要介绍GPS信号数据解调算法的基础上,通过比较数据解调的几种实现方案的优缺点,提出了一种利用PicoBlaze处理器加专用硬件以时分复用的方式同时对12路GPS信号进行数据解调的方案,该方案设计灵活,资源占用少,实际测试验证了整个设计的有效性。A algorithm for data decoding from GPS signals is presented. The algorithm, compared with other algorithms, is based on an architecture of the PicoBlaze processer with some co-processing circuits, which decodes 12-channel GPS signals in the time-divided method. The implementation of the algorithm in FPGAs proved validity and is less hardware resource requirement and is more flexible.
