Joint channel and carrier offset estimation in a multiuser CDMA system
Samir Attallah, Hongyi Fu · IEEE Communications Letters · 2002
We investigate the problem of CDMA multiuser detection in the presence of a small residual carrier offset. We propose, in particular, a method based on the generalized eigenvalue problem for efficiently estimating the channel response and the carrier offset blindly. Simulation results are given to verify the validity of the proposed method.
