FIR H-infinity equalization

We approach finite impulse response (FIR) equalization problem from an H (c hi) perspective. First, we formulate the calculation of the optimal H (infi nity) performance for a given equalization setting as a semidefinite progra mming (SDP) problem. H (infinity) criterion provides a set of FIR equalizer s with different optimality properties. Among these, we formulate the calcu lation of risk-sensitive or minimum entropy FIR filter as the constrained a nalytic centring problem and mixed H (2)/H (infinity) problem as another SD P. We provide examples to illustrate the procedures we described. (C) 2001 Elsevier Science B.V. All rights reserved.
