Blind MIMO paraunitary equalizer
نویسندگان
چکیده
This paper introduces a new Blind Source Separation algorithm for convolutive mixtures. In addition to separate sources, this algorithm respects the paraunitary property of the model considered, obtained after whitening observations. In order to do this, the equalizer is factorized in a novel manner. After a presentation of theoretical results, a numerical algorithm is then derived. This algorithm is based on the solution of a polynomial system, which some values of output cumulant multi-correlations enter. Simulations and performances of the numerical algorithm are presented in the last section. ICASSP’03, Hong-Kong, 6-10 April 2003

Blind paraunitary equalization
In this paper a blind MIMO space-time equalizer is described, dedicated to convolutive mixtures when observations have been pre-whitened. Filters preserving space-time whiteness are paraunitary; a parameterization of such filters is proposed. Theoretical developments then lead to a numerical algorithm that sweeps all pairs of delayed outputs. This algorithm involves the solution of a polynomial...

متن کاملA Multidimensional Phase - Locked Loop for Blind Equalization of Multi - Input Multi - Output Channels
— We present a new technique for blind equalization of multiple-input multiple-output (MIMO) communication channels. In scalar channels it is common to follow a blind equalizer adapted according to the constant-modulus algorithm (CMA) by a phase-locked loop to compensate for carrier frequency offset. We generalize this structure to multiple dimensions , and propose to follow a blind MIMO equali...

This paper shows how the application of MIMO (multiple-input multiple-output) communication methods can enhance telemetry systems. The main contribution of MIMO to the communication system is improving spectral efficiency by exploiting spatial diversity of multiple antennas. For communications using high order QAM modulated signals, a blind MIMO equalizer is proposed in earlier works. In this w...
