Figure 3.23: Profile of the Uplink Simulator56
Chapter 4Simulation ResultsThis chapter presents the simulation results for the WCDMA system at different channelconditions. Simulation results include BER/Frame Error Rate (FER) vs E b /N 0 and BER vsNumber of interferers. Improvement in BER due to error correction coding scheme is shownfor a 9.6 kbps uplink service.4.1 Uplink Simulation ResultsThe following figures show the BER vs E b /N 0 curves for different number of users.The spreading factor at the data channel is 32. The channels are Indoor channel andVehicular A Outdoor Channel. The simulation resolution is 5 samples per chip. We assumethat the received signals from all the users at the base station have equal power, i.e. we haveperfect power control.57
