Effect of Spreading Bandwidth on DS-CDMA Reverse Link Capacity
Hirohito Suda, Fumiyuki Adachi · 1999
this paper, we consider the two di#erent data rates, 8 and 64 ksymbol/s (ksps), and various propagation channel parameters, the number of resolvable paths L =1--8, shadowing standard deviation # =6--10 dB, and shadowing correlation # =0.1--0.9. The reverse link capacities of 1.25 and 5 MHz are evaluated by computer simulation assuming perfect transmit power control and ideal coherent detection.Section 2 describes the computer simulation model and procedure.In this paper, to compare the link capacities of di#erent bandwidths and di#erent data rates, we define the capacity in terms of the throughput (ksps)/cell/MHz.Section 3 presents the simulation results and discusses the e#ects of various propagation parameters of channel.
