On the performance of TDD-TD/CDMA architectures with heterogeneous traffic

Abstract

This paper determines the capacity of a TDD- TD/CDMA architecturewhich supports different classes of subscribers and adopts aninterference-driven admission control policy. The blocking and theoutage probability of the system users are evaluated under varioustraffic conditions for several uplink/downlink configurations ofthe time slots, demonstrating that the time division full duplexapproach needs a careful tuning in order to maximize systemcapacity. Our work further shows that even when data traffic playsthe predominant role, the TDD system can satisfyingly cope withremarkable traffic loads and support several Erlangs of traffic percell.
