Subspace-based joint time-delay and frequency-shift estimation in asynchronous DS-CDMA systems

A subspace-based algorithm for joint time-delay and frequency shift estimation in asynchronous DS-CDMA systems is proposed. The algorithm is near-far robust, requires no preamble, is well suited to fading channels, and can be used for both single-user or multiuser estimation.
