Convergence analysis of blind equalization algorithms using constellation-matching
Lin He, S.A. Kassam · IEEE Transactions on Communications · 2008
Two modified blind equalization algorithms are analyzed for performance. These algorithms add a constellation-matched error term to the cost functions of the generalized Sato and multimodulus algorithms. The dynamic convergence behavior and steady-state performance of these algorithms, and of a related version of the constant modulus algorithm, are characterized. The analysis establishes the improved performance of the proposed algorithms.
