本文提出了CPM的非相干解调与2状态格状译码的方法,并对GMSK信号进行了误码性能的模拟。结果表明:GMSK的2状态格状译码的比特差错性能,远远优于常规的1比特差分解码的GMSK的比特差错性能。
In this paper, the non-coherent demodulation and 2-state trellis decoding of CPM are proposed, and the performance of GMSK signal is simulated. The results show that the bit error performance of GMSK in 2-state trellis decoding is much better than that of GMSK in conventional 1-bit differential decoding.
