On the Flow-Level Delay of a Spatial Multiplexing MIMO Wireless Channel
The MIMO wireless channel offers a rich ground for quality of service analysis. In this paper, the authors present a stochastic network calculus analysis of a MIMO system, operating in spatial multiplexing mode, using Moment Generating Functions (MGF). They quantify the spatial multiplexing gain, achieved through multiple antennas, for flow level Quality of Service (QoS) performance. Specifically they use Gilbert-Elliot model to describe individual spatial paths between the antenna pairs and model the whole channel by an N-State Markov Chain, where N depends upon the degrees of freedom available in the MIMO system.
