Abstract
This paper presents a hybrid algorithm for estimating Gilbert's channe l model parameters from an experimental error-gap distribution. A stoc hastic simulated annealing algorithm is applied to determine automatic ally a set of good starting points, which are then used by the determi nistic gradient algorithm for faster convergence to the global optimum . Simulation results indicate that, for channel characterization, this hybrid strategy provides an ideal compromise between modelling accura cy and convergence time.
