    为了正确进行非正弦时域正交调制通信系统解调,利用脉冲间的时域正交性分离调制脉冲。在重点分析非正交情况下系统解调性能和脉冲间互相关性特点的基础上,提出了在调制端采用选择脉冲的方法,仿真结果表明,该种方法在一定程度上提高了系统的解调性能。

    The orthogonality of pulses is used to demodulate the signal in the non-sinusoidal orthogonal modulation system. By analysis of the performance of the system and cross-correlation of the pulses, the pulse-selection method is provided to improve the performance of the demodulation of the system. The simulations demonstrate that the performance of demodulation is improved.
