NON-SQUARE BLIND SOURCE SEPARATION UNDER COHERENT NOISE BY BEAMFORMING AND TIME-FREQUENCY MASKING
NON-SQUARE BLIND SOURCE SEPARATION COHERENT NOISE BY BEAMFORMING TIME-FREQUENCY MASKING
2015/9/29
To be applicable in realistic scenarios, blind source separation approaches should deal evenly with non-square cases and the presence of noise. We consider an additive noisemixing model with an arbitr...

Bit-Interleaved Coded Multiple Beamforming Perfect Coding
2010/12/8
When the Channel State Information (CSI) is known by the transmitter as well as the receiver, beamforming techniques that employ Singular Value Decomposition (SVD) are commonly used in Multiple-InputM...
