摘要
研究了由相位谱重构有限长离散信号，即幅度补偿问题。根据以归一化相关系数对经典迭代法的收敛性进行的证明，讨论作为经典迭代法改进算法的松弛迭代法的收敛问题。列举了三种松弛迭代法的修正方法，并进行了比较。
This paper studies the problem of signal reconstruction from spectral phase. The convergence problem of relaxed iterative algorithm is discussed based on the convenience proof using normalized correlation factor. Three modification methods are presented and compared. The first modification method presented in this paper, of relaxed iterative algorithm with order one or two, is recommended.
