The author has applied bcpc code to two fields . one is a frequency hopping ( fh ) communication system . theoretic analysis and simulation results show bcpc sequence features ideal random performance , good hamming correlation property and wide fll gap 将scqc码应用于跳/扩频通信系统( fh - ss )的码变型(即反转移相键控)器中,分析了scqc码序列的性能。
