A Markov chain-based queueing model is developed for a cross-layer performance analysis of a wireless network based on adaptive modulation and coding (AMC) at the physical layer and truncated automatic repeat request (ARQ) error control at the data link layer. This model generalizes previous results by using a first-order two-dimensional Markov chain to model the wireless fading channel. Furthermore,...
In this paper the performance of the reverse link of a multicell DS-CDMA system with coexisting open-loop and closed-loop power controlled users transmitting heterogeneous traffic is analyzed. Real-time and non-real-time traffic performance expressions are obtained. The analysis includes a different channel coding scheme for each traffic type selected in accordance to their specific QoS requirements...
