Description/Abstract

This paper is concerned with the comparative study of fixed channel allocation (FCA) and dynamic channel allocation (DCA) algorithms [-3], many of which were proposed and studied, in terms of the achievable Grade-of-service (GOS), by Chuang et al through-out the past few years. The performance gains that may be obtained using adaptive antenna arrays at the basestation are also determined, along with a range of further performance measures, such as carried traffic, call blocking, call dropping, the probability of low quality access and outage. The comparisons are carried out for a range of channel allocation techniques under identical uniform traffic conditions, where all users seemlessly roam across the simulation area, rather than simply assigning them to arbitrary, uncorrelated, but essentially stationary random positions.
