Least-squares CMA with decorrelation for fast blind multiuser signal separation
نویسندگان
چکیده
A blind algorithm with implicit signal selectivity capability is proposed. The algorithm is an evolution of the original multiuser constant modulus algorithm of [1]. The new algorithm features a least-squares type updating rule for fast convergence rate and an adaptive control of the weight of the decorrelation term which improves the steady-state error variance. The expected improvements of the proposed algorithm are verified through simulations with smart antennas in a spatial-division multiple access system.

The Generalized Constant Modulus Algorithm Applied to Multiuser Space-Time Equalization
The generalized constant modulus criterion and algorithm (GCMA) was proposed in [1] as a blind equalization technique for combating inter-symbol interference in single-user systems. In this paper we extend this concept for the blind separation and equalization of multiple users in presence of inter-symbol interference. The proposed criterion and algorithm can be viewed as a generalization of CM...
متن کاملMultiple-input multiple-output least-squares constant modulus algorithms
In this paper, we propose novel blind separation techniques for multiple-input multiple-output systems based on least-squares constant modulus algorithm (LSCMA). To ensure that each output signal is extracted from different input signals, the proposed algorithms have been derived by using successive interference cancellation and Gram-Schmidt orthogonalization procedure. The performance is obser...
متن کاملBounds for the mixing parameter within the CC-CMA algorithm applied in non ideal multiuser environments
We derive new bounds for the mixing parameter, , within the cross-correlation constant modulus algirithm (CC-CMA) for blind source separation and equalization in non-ideal multiuser environments. Channel undermodelling and noise are considered when the complex sources are circularly symmetric. These tighter bounds are obtained by surface topography of the error performance surface of the CC-CMA...
متن کاملUse of Decorrelation Procedure for Source and Echo Suppression
The so-called semi-blind source separation (SBSS) is an extension of BSS when some signals can be directly and individually measured. SBSS can be used to implement multi-channel acoustic cancellation (MCAEC) without the need for double-talk detection. However, traditional MCAEC approaches based on least mean-square (LMS) lead to a non-unique solution due to correlated sources formed when a sing...
متن کاملConvolutive Blind Source Separation based on Multiple Decorrelation
| Acoustic signals recorded simultaneously in a reverberant environment can be described as sums of di erently convolved sources. The task of source separation is to identify the multiple channels and possibly to invert those in order to obtain estimates of the underling sources. We tackle the problem by explicitly exploiting the non-stationarity of the acoustic sources. Changing crosscorrelati...
