Resumo: Input orthogonalization methods for supervised and blind identification of third-order MIMO Volterra communication channels are considered. In the supervised case, we extend the use of orthonormal polynomials to MIMO Volterra systems. In the blind case, we propose an original solution for channel identification based on the use of state-dependent modulation code schemes with PSK signals. Several channel estimation methods using input orthogonalization are presented and their performances are evaluated by means of computational simulations.

Dans le cas supervisé, la méthode proposée consiste en une extension de l’utilisation des polynômes orthogonaux aux systémes de Volterra MIMO. Dans le cas aveugle, on présente une solution originale pour l’identification des canaux à l’aide de codes de modulation avec des signaux PSK. Des algoritmes d’estimation de canal basés sur l’utilisation de ces méthodes d’ortogonalisation sont présentés et leurs performances sont évaluées à l’aide de simulations numériques.Colloque GRETSI2012-12-07T14:26:46Z2012-12-07T14:26:46Z2007info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/conferenceObjectapplication/pdfFERNANDES, C.
