Abstract :
Many technologies for multi-user detection have been put forward to overcome the problem of the near-far effect in a CDMA system. Two algorithms for a blind adaptive successive interference canceling receiver with few operation quantities are proposed. Compared with the LMS one, they not only have the same performance, such as convergence rate and high SINR, but also overcome some disadvantages of normal operation quantities and non-convergence of of the weight vector
