本文基于连续相位的思想，设计了一种吞吐量高效的调制方法，即连续相位扩展的二进制相移键控(CPEBPSK)，以满足通信系统日益增长的性能要求。采用一种适用于超窄带(UNB)通信二进制调制的通用方法，对相应的功率谱进行了详细的分析。仿真结果验证了理论频谱分析的正确性，证明了该超宽带系统具有较高的频谱利用率。在此基础上，研究了CP-EBPSK技术的带宽，指出CP-EBPSK技术属于UNB吞吐量高效通信的范畴。
In this paper a throughput efficient modulation method based on the idea of continuous phase is devised, namely the continuous phase extended binary phase shift keying (CPEBPSK), which satisfies increasingly greater demand for the performance of communication systems. The detailed analysis of the corresponding power spectrum is derived by a universal way that is suitable for the binary modulation of ultra narrow band (UNB) communications. Simulation results illustrate the validity of theoretical spectrum analysis, which prove that this UNB system having high spectral efficiency. On this basis, the bandwidth is studied that indicates the CP-EBPSK technology belongs to the category of the UNB throughput-efficient communications.
