FIR H∞ equalization
Alper Tunga Erdogan, Babak Hassibi, T. Kailath · 2005
We approach FIR equalization problem from an H∞ perspective. First, we formulate the calculation of the optimal H∞ performance for a given equalization setting as a semidefinite programming (SDP) problem. H∞ criterion provides a set of FIR equalizers with different optimality properties. Among these, we formulate the calculation of risk sensitive or minimum entropy FIR filter as the constrained analytic centring problem and mixed H2/H" problem as another SDP. We provide an example to il- lustrate the procedures we described.
