An efficient blind identification algorithm for multichannel FIR systems using linear prediction
In this paper, an e cient blind identi cation algorithm for multichannel FIR systems was proposed based on a deterministic model of the channel input. By decoupling the multichannel identi cation, the proposed method was able to estimate individual channel responses separately without having to solve for the augmented channel responses. The algorithm was implemented using linear prediction tech...
متن کاملThe Complex Multichannel Lms Algorithm for Adaptive Blind System Identification
Existing adaptive algorithms for blind SIMO system identification are implicitly derived for real signals. In this paper, we extend the multichannel LMS algorithm to the complex case. This is useful, for example, in multirate implementations of the algorithms where the subband signals are usually complex. With this algorithm, the channels are identified correctly up to a complex multiplicative ...
متن کاملA blind multichannel identification algorithm robust to order overestimation
Active research in blind single input multiple output (SIMO) channel identification has led to a variety of second-order statistics-based algorithms, particularly the subspace (SS) and the linear prediction (LP) approaches. The SS algorithm shows good performance when the channel output is corrupted by noise and available for a finite time duration. However, its performance is subject to exact ...
متن کاملGaussian Maximum Likelihood Blind Multichannel Multiuser Identification
We consider a Spatial Division Multiple Access (S.D.M.A.) situation in which p users operate on the same carrier frequency and use the same linear digital modulation format. We consider m > p antennas receiving mixtures of these signals through multi-path propagation (equivalently, oversampling of the received signals of a smaller number of antenna signals could be used). Current approaches to ...
متن کاملIdentifiability Conditions for Blind and Semi-blind Multiuser Multichannel Identification
We explore the identifiability conditions for blind and semi-blind multiuser multichannel identification. Starting with the deterministic approach, we compare the identifiability conditions on the channel and the sources of training sequence based channel identification, blind and semi-blind channel identification. Further on, we use the stochastic approach with Gaussian priors for the source s...
