| Abstract: | 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. |
