基于串行干扰消除的非正弦系统解调方法

Demodulation method for non-sinusoidal orthogonal modulation system based on SIC

摘要: 在非正弦时域正交调制系统接收端，为了提高非严格正交脉冲组的解调性能，弱化脉冲组的正交性约束，采用一种基于串行干扰消除的白化变换解相关检测法进行多脉冲联合解调.结果表明：该方法能够改善非正弦时域正交调制系统的性能，且优于传统白化变换解相关法，特别是对于幅度不等的情况，其性能改善程度较大.

Abstract: A decorrelation method of whiting transform based on successive interference cancellation(SIC)is proposed for improving the performance of demodulation of the non-sinusoidal orthogonal modulation system in time domain.The simulations demonstrate that the performance of the proposed method is better，especially when pulses have different amplitudes.
