Downlink interference analysis in DS-CDMA for unequal power requirements: The dirty user problem

Reed, Mark; Hanlen, Leif

Description

Downlink interference analysis within direct-sequence code-division multiple-access (DS-CDMA) systems is considered in this paper. Although orthogonal codes are used at the base-station transmitter, multi-path and different power requirements of terminals mean that substantial multiple access interference is suffered at the terminals. With the multitude of terminals available for 2G and 3G systems, inefficient terminal design leads to the "Dirty User Problem", that is, where a terminal requests...[Show more]
