Abstract

In this paper, we propose an algorithm for frequency domain adaptive Doppler shift estimation in the presence of multiple Doppler subpaths in DS-CDMA systems. By modeling doubly selective channel with a basis expansion model (BEM), the proposed method works based on Expectation-Maximization (EM) algorithm and can accurately estimate Doppler shifts. A complete Cramer-Rao Lower Bound (CRLB) analysis of the estimation algorithms is also provided.
