Abstract

In this paper, we present a novel two-hop-relay WCDMA cellular system with queuing capability, where a call can be queued in the incoming buffer at the congested Base Transceiver Station if no channel is immediately available, so as to reduce the call blocking probability. We develop an analytic model based on multidimensional Markov chains. Then based on this model, we can calculate the average system transmission rate, the queuing delay and the system call blocking probability respectively. Finally, through experimental simulations, we analyze the impact of the various parameters on the performance for the system.
