Abstract

This article analyses the data throughput of the uplink of a DS-CDMA cellular network, using random and Walsh spreading sequences, the matched filter and multiuser detector decorrelator (MUD-D). The mathematical modelling of the system described above takes into consideration an additive white gaussian noise channel with exponential path loss, perfect power control and internal and external co-channel interference. Within this context different modulations such as QPSK and M -QAM (16, 64 and 256-QAM) are used.
