Abstract :
In this paper, a novel blind adaptive multiuser detection is proposed. The computational complexity of this algorithm is O(NL), where N is the spread gain, and L is the window length. The algorithm has the good steady state performance and very fast convergence. Simulations indicate that the performance of this algorithm is better than that of CMOE and can be used in a dynamic multiple-access channel where interference may enter or exit the channel
