Blind multiuser detection for code-hopping DS-CDMA signals in asynchronous multipath channels.

Blind detection of a desired user's signal in a code-hopping (CH) direct sequence code-division multiple access (CDMA) system is considered. In CH CDMA systems each user switches between a predetermined set of short-code sequences. A user signal in such systems may be treated as the superpositi...
