Research output: Contribution to journalArticlepeer-review


In this paper, we study the performance of quality-based voice/data CDMA system where new and handofi, traffic are considered. A call request for handoff data queues up if the signal-to-interference ratio exceeds a predefined threshold while priority is given to handofl, voice calls by reserving some channels exclusively for them. The transmission rate of data users may vary according to measured SIR value. Important performance measures of the system such as blocking probability and system capacity for voice or data calls for proposed schemes are presented and compared.
