Direct blind multichannel identification

Miloud Frikel, Wolfgang Utschick, Josef A. Nossek

Abstract: In this paper, different techniques for the estimation of the signal parameters and/or the channel coefficients for single-input/multiple-output systems, arc presented. These methods arc based, cither on the use of a small part of observations or on the minimization of a quadratic form with quadratic constraint. Simulations have been established and these techniques arc compared to the classical approaches.
