Performance analysis of RLS constant modulus algorithm in DS-CDMA system
Xin Wang, Xuelan Zou, Guangwen Li · 2008
In this research, we analyze the performance of recursive least squares constant modulus equalization in direct spread code division multiple access system. The expressions for excess mean square error (EMSE) are derived by feedback analysis in both the stationary and non-stationary channels. With EMSE, the relationship between the stochastic gradient descent and the recursive least square in CDMA is obtained. Simulation results demonstrate it.
