In this letter, we present a performance analysis of the blind adaptive multiuser detector (MUD) proposed in Miguez and Casredo (1998), which is based on the 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.
