Subspace-based joint time-delay and frequency-shiftestimation in asynchronous DS-CDMA systems
Miljko M. Eric, M. Obradović · Electronics Letters · 1997
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 singleuser or multiuser estimation.
