摘要：

The problem of time delay estimation (TDE) has many approaches and a large field of applications, making it an important research issue. For specific air traffic control systems, time delay estimation is a primary step for speech enhancement. In this paper we introduce two new TDE methods, based on cross power-spectrum phase (CSP), combining previous efficient methods that use accumulating cross power spectrum, whitening and coherence. We show that the proposed methods bring an accuracy improvement of more than 5%, while being 5% to 20% faster.
