Identification of active users in synchronous CDMA multiuser detection.

Identification of active users in synchronous CDMA multiuser detection.

The level of multiple access interference (MAI) in code division multiple access (CDMA) communication systems is a time-varying parameter related to the number of active users. Almost all existing multiuser detection schemes were designed based on a priori information of the active users. In many si...
