Abstract :
Many IS-95 CDMA networks currently deployed in the field are forward link capacity limited. The introduction of IS-2000 is intended to improve forward link performance and increase system capacity. However, the performance improvement provided by IS-2000 will vary with propagation environment. A technique for collecting forward channel impulse response measurements using IS-95 pilot signals is presented. This technique is used to characterize the forward channel in residential and urban regions in Calgary, Canada. The propagation data is then processed in a simulation in order to generate a comparison of IS-95 and IS-2000 performance that is specific to these environments. The results illustrate how the propagation environment can affect the performance improvement provided by IS-2000
