摘要

本文研究了从傅里叶变换相位出发的信号重构问题。具体来说，我们将研究这个问题的两个方面。首先，我们讨论了短时傅里叶变换(STFT)的相位谱对信号的重构。接下来，我们研究了从部分相位信息中恢复信号的问题。我们介绍了部分相位重构的研究结果，并讨论了这些结果在语音分析和编码中的应用。

Reconstruction from Fourier transform phase with applications to speech analysis

This paper addresses the problem of signal reconstruction from Fourier transform phase. In particular, we examine two aspects of this problem. First, we discuss signal reconstruction from the phase spectrum of the short-time Fourier transform(STFT). Next, we examine the problem of signal recovery from partial phase information. We present the results of our studies on reconstruction from partial phase and discuss the application of these results in speech analysis and coding.
