摘要
木文研究了长度N=2~m的P_3和P_4码的相位分布规律及其基本相位集。解决如何将移相型离散调制器用于Lewis码的一系列工程设计问题。
This paper discusses the modulation Problem about Lewis Codes. The basic phaseset and phase distribution rule of P_3 and P_4 with codelength N=2~■ have been studied. And try tosolve a series engineering problems of using phase shift discrete modulator in Lewis codes.
