Abstract: The modulated signal is very sensitive to timing jitter in nonsinusoidal orthogonal modulation communication system.Timing jitter can degrate demodulation performance greatly.A novel antitimingjitter receiving method is proposed for the issue.Based on equivalent lowpass signal of nonsinusoidal orthogonal modulation signal，timing jitter can be calculated from correlation result between each modulated signal and sinusoidal or cossinusoidal siganl.The phase of template signal can be amended timely so as to remove the timing jitter effect on system performance.Simulation result shows that the timing jitter has no effect on the demodulation performance when it is controlled in 1%×Ts.This method not only overcomes the known methods limitation but also keeps the optimum output signalnoiseratio.
