Performance evaluation of a reservation TDMA protocol forvoice/data transmission in personal communication networks withnonindependent channel errors

摘要

This paper deals with a random reservation TDMA protocol able tonsupport constant bit-rate services as well as variable bit-ratenservices. In particular, we consider here the case of voicencommunications and data transmissions in a fading channel environmentnwith nonindependent errors. Voice terminals are assumed to have highernpriority than data terminals, in accessing the shared channel. Ansuitable analytical approach is proposed in order to evaluate the datanand voice subsystem performance. Computer simulations are also shown innorder to validate the obtained analytical predictions. The results shownnhere highlight that the proposed protocol permits an efficientnintegration of voice and data transmissions in the same wireless networkneven in the presence of a nonideal transmission channel
