PWPM信号的功率谱研究
ANALYSIS OF POWER SPECTRUM OF PWPM
【摘要】 对脉冲宽度、位置联合调制(pulse width and position modulation)简称 PWPM 方式的随机信号序列功率谱进行了研究,文献[1]的理论结果显示 PWPM 随机信号序列功率谱中存在符号(symbol)同步信号离散谱成分,这有利于在接收端正确接收 PWPM 信号.用计算机模拟估计了 PWPM 随机信号序列的功率谱.其结果也表明了 symbol 同步信号的存在.
【Abstract】 This paper presents fundamental analysis of power spectrum of random se-quence of pulse width and position modulation(PWPM)signals.The theoritic result indicatesthat there is a symbol synchronous signal in the random sequence.This symbol synchronoussignal can improve receiver’s performance.The estimation results of power spectrum of ran-dom sequence of PWPM signals are also presented by simulating random sequence of PWPMsignals with computer.The estimation results show that there is a symbol synchronous signal.
