Parameter estimation in CDMA multiuserdetection using cyclostationary statistics
Franco Mazzenga, Francesco Vatalaro · Electronics Letters · 1996
The authors propose a simple algorithm to jointly estimate the amplitude, phase, and time delay of each individual signal in the multiuser detection of a code division multiple access (CDMA) signal. The algorithm exploits the cyclostationary nature of the CDMA signal by estimating its cyclic and conjugate cyclic spectra. Its complexity increases linearly with the number of users.
