摘要:
针对现有串扰减小方法效果有限、成本高、资源消耗多等问题,提出了一种基于信道传输矩阵逆矩阵减小微带线间串扰的方法。该方法通过将信道传输矩阵化为单位阵来实现串扰减小。根据理论分析设计了该方法的电路结构。仿真结果表明,使用该方法进行串扰抵消后串扰幅度和抖动都有明显改善,且该方法的电路结构简单。

Abstract:
In view of the problems such as limited effectiveness,high cost and high resource consumption of the existing crosstalk reduction methods,a crosstalk reduction method based on the inverse matrix of channel transmission matrix is proposed.This method reduces the crosstalk by converting the channel transmission matrix into a unit matrix.The circuit structure of this method is designed according to the theoretical analysis.The simulation results show that the crosstalk amplitude and crosstalk-induced jitter are improved significantly after using this method,meanwhile the circuit structure of this method is simple.
