Blind source separation for BLAST

2002 14th International Conference on Digital Signal Processing Proceedings. DSP 2002 (Cat. No.02TH8628), 2003
We present a new blind source separation (BSS) approach for Bell Labs layered space-time (BLAST) communication system. The proposed algorithm is derived from the multimodulus algorithm (MMA) and employs the Gram-Schmidt orthogonalization procedure. The basic idea is to adjust the real and imaginary parts of the equalizer matrix separately and then ...

Blind and semi-blind source separation

2007
After a brief state-of-the-art description, we introduce the fundamental concepts of independent component analysis, which is the reference technique we used to solve the blind- or semi-blind source separation problem for astrophysical images. The specific aspects of this problem are then presented, and the results we obtained with some specific ...

Subband Based Blind Source Separation

2005
In this chapter, we address subband-based blind source separation (BSS) for convolutive mixtures of speech by reporting a large number of experimental results. The subband-based BSS approach offers a compromise between time-domain and frequency-domain techniques.

Frequency-Domain Blind Source Separation

2007
This chapter discusses the frequency-domain approach to the blind source separation (BSS) of convolutively mixed acoustic signals. In this approach, independent component analysis (ICA) is employed in each frequency bin to calculate the frequency responses of separation filters.
