Second Order Blind Identification

Description

Python modules for performing second-order blind identification. This is a blind source separation technique based on second-order statistics.

For more info see (not my paper!):

Belouchrani, A., et al. “A Blind Source Separation Technique Using Second-Order Statistics.” IEEE Transactions on Signal Processing: A Publication of the IEEE Signal Processing Society, vol. 45, no. 2, Feb. 1997, pp. 434–44, doi:10.1109/78.554307.

This is a work in progress. It seems to work but hasn't been thoroughly tested/documented
