The project is enhancement of acoustic echo canceler using blind source separation. Here BSS is implemented before AEC to improve the performance of the AEC. The reason for implementing the BSS is since the AEC freezes adaption during double talk.

The BSS part has already been done. I am looking for the acoustic echo cancellation part using NLMS algorithm with a double talk detector. The aim is to get better results with BSS+AEC rather than just AEC. The attached paper gives more details about the project.

What I am looking for is,
1. AEC with NLMS & double talk detector.
2. Graphs showing comparison of Error return loss enhancement, with BSS+AEC and only AEC.
3. Graph showing the Double Talk Detection using the best possible method(Cross- correlation).
4.Better signal reconstruction of desired signall(Local speech) after the BSS and AEC.

I am attaching the previous work done on this i.e. matlab file. This is extension of that particular matlab file. In the BSS part. there is a...
