F. Mazzenga et F. Vatalaro, PARAMETER-ESTIMATION IN CDMA MULTIUSER DETECTION USING CYCLOSTATIONARY STATISTICS, Electronics Letters, 32(3), 1996, pp. 179-181
The authors propose a simple algorithm to jointly estimate the amplitu
de, phase, and time delay of each individual signal in the multiuser d
etection of a code division multiple access (CDMA) signal. The algorit
hm exploits the cyclostationary nature of the CDMA signal by estimatin
g its cyclic and conjugate cyclic spectra. Its complexity increases li
nearly with the number of users.
