由相位谱重构离散信号的收敛性

Convergence of Discrete Signal Reconstruction from Its Spectral Phase

研究由相位谱重构有限长离散信号，即幅度补偿问题的收敛性。文章独立地以归一化相关系数对经典迭代法的收敛性进行了证明。通过该证明，可体会到经典迭代法之所以可进行信号重构的机理。

This paper presents an unique proof of the convergence of classic iterative algorithm for signal reconstruction from spectral phase. The proof is based on usage of the normalized correlation factor.
