摘要：

This paper deals with a random reservation TDMA protocol able to support constant bit-rate services as well as variable bit-rate services. In particular, we consider here the case of voice communications and data transmissions in a fading channel environment with nonindependent errors. Voice terminals are assumed to have higher priority than data terminals, in accessing the shared channel. A suitable analytical approach is proposed in order to evaluate the data and voice subsystem performance. Computer simulations are also shown in order to validate the obtained analytical predictions. The results shown here highlight that the proposed protocol permits an efficient integration of voice and data transmissions in the same wireless network even in the presence of a nonideal transmission channel.
