Abstract

This letter presents a blind method for joint carrier offset and code timing estimation in direct-sequence code-division multiple-access systems. The proposed method is arrived at by exploiting the subspace structure of the observed signal along with analytical tools of polynomial matrices. It yields an algebraic solution which avoids a multidimensional search over the parameter space, a procedure that is computationally involved and often suffers local convergence. The proposed method is multiaccess interference resistant. Furthermore, it can be used in time-varying, multipath fading channels.
