Simulation and performance analysis of Cellular Digital Packet Data

Abstract

As the wireless telecommunications industry becomes more widely accepted, the need for mobile data communication has followed the rise in mobile voice communication. Cellular Digital Packet Data (CDPD) offers an unobtrusive data service that overlays the existing Advanced Mobile Phone Service (AMPS) in a cost effective manner that will be attractive to most service providers. Using idle time between voice traffic, CDPD uses Gaussian Minimum Shift Keying (GMSK) to send bursts of Reed-Solomon encoded information while channel hopping to avoid interfering with voice transmissions. This thesis assesses the performance of CDPD for different channel environments through simulation. Specifically, Gaussian noise, Rayleigh fading, co-channel interference models are incorporated to identify the performance of the system.
