一种多数字调解系统中的最优掩膜计算方法

Abstract

本发明提供一种多数字调解系统中的最优掩膜计算方法。该方法过计算滤波后的信号和对应的理想环境接收信号之间的最小二乘误差总和的方式找到数字调解系统的埃尔米特变换矩阵及其的掩膜系数向量最优化设计的目标函数,使用奇异值分解法并采用一个迭代算法去解决该目标函数的这个最优化问题,从而找到了一个可追踪方法去解决这个最优化问题,且不需要使用计算机数值辅助设计工具造成资源的浪费。
The invention provides an optimal mask calculation method in a multiple digital mediation system. The method is that a Hermite transformation matrix of the mediation system and an optimally designed objective function of a mask coefficient vector are found through a way of a minimal LS (Least Squares) error sum between a signal after the filtering calculation and a corresponding ideal environment receiving signal, and an optimization problem of the objective function is solved by using an SVD (Singular Value Decomposition) method and an iterative algorithm, so as to find out a traceable method to solve the optimization problem, and the resources waste caused by an aided design tool of computer numerical values can be prevented.
