Fast Adaptive Channel Estimation Algorithms for CDMA Systems
Amar A. El-Sallam, Abdelhak M. Zoubir · 2006
The paper presents adaptive blind channel estimation and tracking algorithms for CDMA systems. Using only the spreading code of the user of interest, three blind estimation algorithms are proposed to estimate the channel response from the received data sequence. The idea is based on minimum variance (MV) receivers. Simulation results show that the proposed algorithms perform better than previously proposed algorithms, also they are less complex and have a fast convergence rate.
