Abstract

This paper studies the multi-user detection of constant modulus algorithm and presents an application of the new algorithm for constant modulus properties. The algorithm uses the fading channel under the discrete received signal equivalent expressions, which derived by matrix operations lies in the mode value of the minimum conditions, the relationship between the receiver equalizer weights and effective spreading code matrix. Simulation results show that the algorithm is effective.
