Improved contrast dedicated to blind separation in communications
نویسندگان
چکیده
Contrast-based separation of sources have a number of advantages. Among others, they are optimal (in a precise sense) in presence of noise of unknown statistics. Here a new contrast is proposed that allows not only to obtain the optimal solution analytically, but also yields better performances in terms of variance of the estimated mixing matrix. This contrast needs source kurtosis to have the same sign, and is thus appropriate to multichannel blind equalization in communications.

متن کاملMANSOUR and KAWAMOTO : ICA PAPERS CLASSIFIED
Since the beginning of the last two decades, many researchers have been involved in the problem of Blind Source Separation (BSS). Whilst hundreds of algorithms have been proposed to solve BSS. These algorithms are well known as Independent Component Analysis (ICA) algorithms. Nowadays, ICA algorithms have been used to deal with various applications and they are using many performance indices. T...
متن کاملSeparation of the EEG Signal using Improved FastICA Based on Kurtosis Contrast Function
Independent component analysis (ICA) is a computational method to solve blind source separation (BSS) problem. In this paper, an improved FastICA based on Kurtosis was proposed to separate EEG signal. It was adopted from the gradient descent algorithm to improve the converge rate. Improved FastICA method was applied to separate EEG signal from a patient who had epilepsy seizure. The separation ...
متن کاملBlind Source Separation Using Modified Contrast Function in Fast ICA Algorithm
A novel contrast function is proposed to be used in fastICA algorithm for Blind Source Separation (BSS). Simulation results show that the proposed nonlinear function used to separate image mixtures, results in faster execution and good quality image separation. Peak Signal to Noise Ratio (PSNR), Improved Signal to Noise Ratio (ISNR), Signal to Noise Ratio (SNR) and Root Mean Square Error (RMSE)...
متن کاملBlind Signal Separation in Communications: Making Use of Known Signal Distributions
We apply maximum likelihood blind source separation [7] to complex valued signals mixed with complex valued nonstationary matrices. This case arises in radio communications with baseband signals. We incorporate known source signal distributions in the adaptation, thus making the algorithms less “blind”. This results in drastic reduction of the amount of data needed for successful convergence. A...
