关於 cross-band and cross-channel speech enhancement techniques

山羊座

我最近有一报告是要研究有关技术的
可是在网上找了很久都找不到什么资料
請問你們有誰了解这方面的学识嗎?
請指教一下
不胜感激

以下是我报告研究的大致上的內容(英文)

Investigating cross-band and cross-channel speech enhancement techniques.

Restoring the desired speech signal from a mixture of speech and background noise has always been given considerable interests in the area of speech processing and communication system. One technique to reduce background noise is by using models of the human auditory system. The models exploit the input signals to both ears of a subject and perform a processing similar to the effective noise filtering performed by the binaural system. Several descriptions on these techniques are available in the literature. The aim of the project is to investigate cross-band and/or cross-channel speech enhancement techniques. Stages involve may include:

1)        Literature review on speech enhancement techniques
2)        Familiarisation with software eg Matlab/Simulink
3)        Understanding key DSP techniques eg FFT, correlation, overlap-add etc
4)        Possible investigations/developments on head-related transfer function, Peissig’s model, amplitude modulation techniques etc
5)        Possible investigation on implementing some algorithms on a hardware (digital signal processor)


希望你們可以尽量帮一帮忙
