Convergence behaviours of an adaptive step-size constant modulus algorithm for DS-CDMA receivers
A convergence analysis of the blind adaptive step-size constant
modulus algorithm (AS-CMA) for direct-sequence code division
multiple access (DS-CDMA) receivers is presented. Analytical
results show similar convergence behaviours of the AS-CMA receiver
and the adaptive step-size stochastic approximation (ASSA)
receiver. Simulations show that the blind AS-CMA algorithm
performs comparably with the non-blind AS-SA in a Markovian
type of nonstationary environment. The robustness of the proposed
algorithm to different settings of the initial step-size is also shown
