Capacity of a CDMA wireless communication system in picocellular environment

Abstract

This paper provides some figures describing the capacity and the Quality of Service (QoS) of the CODIT (UMTS Code Dlvision Testbed) system in an indoor environment, taking into account both voice and data services. These evaluations are part of the comparison activities between the CODIT and ATDMA (Advanced TDMA Mobile Access) systems that have been performed within the Special Interest Group SIGS.[*] The simulation scenario has been defined in order to make easier the comparison between the two systems and not for the optimisation of the respective capacities.

Performance of multirate CDMA transmission in cellular environment

“…however. 6 user case performs better beyond 18 clB. It is due ro the effect of interference (section 3.6) that has been imposed by the user combination (table 3.1) for these two cases.…”

“…It is seen that efficient channel management can increase the systern capacity by many folds [ 6 ] . Microcells provides increase in capacity of the system whiie macrocells allow fast moving terminais without excessive handoffs thus improving communication quality.…”
