Abstract :
The UMTS W-CDMA radio interface is characterized by great flexibility and a variety of different physical and logical channel types, rates and protections are possible, by choosing suitable parameters, such as spreading factors, code rates and ARQ schemes. In this paper we present the results, obtained by a detailed simulation, about the effect of several parameters and system alternatives on the capacity of the downlink shared channel
