ABSTRACT:
A multiuser detector for a CDMA system for real-time processing. Interference information of cross correlation from the signals of different users is processed to enhance the signal-to-noise ratio by suppressing the interference noise in a multiple-stage processing. A sampling processor is implemented to obtain at least two sets of data for each user with different integration times. The operation of the detector is dynamically adjusted to the operating condition of the CDMA system in a near real-time manner.
