摘要：

We propose a new framework to analyze performance considering finite-length queuing and adaptive modulation and coding (AMC) for multi-user VoIP services in wireless communication systems. We formulate an uplink VoIP system as two-dimensional discrete-time Markov chain (DTMC) based on a Markov modulated Poisson process (MMPP) traffic model and MCS (modulation and coding scheme)-level set transition reflecting users' channel variations. We extend transition modeling of MCS-level for single-user to transition modeling of MCS-level set for multi-user. Throughout our DTMC formulation, we present various performance metrics, such as average queue-length, the average number of arrived and serviced packets, and packet dropping probability.
