The impact of code allocation on the multiple access interference in WCDMA systems

Code allocation has a significant impact on the performance of Code Division Multiple Access (CDMA) systems. For the uplink direction, in 3G Wideband CDMA (WCDMA) cellular systems, orthogonal codes are employed to differentiate the physical channels of one transmitter and Pseudo Noise (PN) sequences are used to provide mutual randomness between the users… (More)
