ABSTRACT Third generation (3G) cellular communication standards are based on Wideband Code Division Multiple Access (WCDMA). The wideband signals experience frequency-selective fading due to multi-path propagation, hence increasing the Multiple Access Interference (MAI). To combat this effect, an efficient channel estimation algorithm, based on the Maximum Likelihood (ML) approach is derived. The algorithm handles the situation of multiuser, and multi-path by estimating a composite Channel Impulse Response (CIR). This estimation is performed in the reverse link, for each user, without needs of estimating each individual channel parameters. This has the achievement of reducing the computational complexity. The efficiency of the proposed channel estimator is measured in terms of Mean Squared Error (MSE), handling capacity, loss due to estimation, as well as resistance to MAI.
