Referenced Contrast: A New Approach to the Blind Deconvolution of MIMO Channels
نویسندگان
چکیده
Contrast-based separation of sources has a number of advantages. Among others, they are optimal in presence of noise. In this work, we propose a new contrast by considering a so-called reference signal that allows not only obtaining the optimal numerical algorithm but also yields better performance in terms of variance of the estimated mixing filter. This contrast needs source kurtosis to have the same sign. Thus, it's appropriate to multichannel blind deconvolution.

Blind Deconvolution Algorithms for Mimo-fir Systems Driven by Fourth-order Colored Signals
In this paper, we propose a new iterative algorithm to solve the blind deconvolution problem of MIMO-FIR channels driven by source signals which are temporally second-order uncorrelated but fourth-order correlated and spatially secondand fourth-order uncorrelated. To achieve our goal, we extend the super-exponential deflation algorithm proposed by Inouye and Tanebe [2] to the case of the blind ...
متن کاملAn Eigenvector Algorithm with Reference Signals Using a Deflation Approach for Blind Deconvolution
We propose an eigenvector algorithm (EVA) with reference signals for blind deconvolution (BD) of multiple-input multiple-output infinite impulse response (MIMO-IIR) channels. Differently from the conventional EVAs, each output of a deconvolver is used as a reference signal, and moreover the BD can be achieved without using whitening techniques. The validity of the proposed EVA is shown comparin...
متن کاملPSO-Optimized Blind Image Deconvolution for Improved Detectability in Poor Visual Conditions
Abstract: Image restoration is a critical step in many vision applications. Due to the poor quality of Passive Millimeter Wave (PMMW) images, especially in marine and underwater environment, developing strong algorithms for the restoration of these images is of primary importance. In addition, little information about image degradation process, which is referred to as Point Spread Function (PSF...

متن کاملSingle-Carrier Frequency-Domain Equalization for Orthogonal STBC over Frequency-Selective MIMO-PLC channels
In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...
