Résumé: In this letter, we present a performance analysis of the blind adaptive multiuser detector (MUD) proposed in [1], which is based on linearly constrained constant modulus (LCCM) criterion. Global convergence of the algorithm with additive white Gaussian noise (AWGN) is proved and two approximate closed-form solutions of the optimum tap-weight vector are derived. Also the validity of analysis is demonstrated by comparing analytical results with simulated results.
