Ignacio Santamarı́a, C. Pantale, Luis Vielva, José Carlos Príncipe · 2002
In this paper a' novel blind equalization algorithm based on stochastic gradien t descent minimization of order-a Renyi's entropy and designed for constant modulus signals is intro duced. The algorithm applies a new nonparametric estima tor for Renyi's. entropy, which has been rec entl y proposed and allows to compute any order of entropy. In compar ison with conventional adaptive blind techniques, such us CMA, the proposed algorithm shows a remarkable increase in convergence' speed with only a moderate increase in com putational cost.
