Abstract :
The uplink performance of a digital cellular radio system that uses DS (direct-sequence) CDMA (code division multiple access) is evaluated. Expressions for bit error probability that account for path loss, multipath-fading, multiple-access interference, and background noise are obtained. Three differentially coherent receivers are considered: a multipath rejection receiver, a RAKE receiver with predetection selective diversity combining, and a RAKE receiver with postdetection equal gain combing. Error correction coding is also considered
