Downlink Performance of a Multi-Carrier MIMO System in a Bursty Traffic Cellular Network

In this paper we analyse the downlink performance of a rank adaptive
multiple input multiple output (MIMO) system in a busty traffic
cellular network. A LTE-Advanced system with multiple component
carriers was selected as a study case. To highlight the advantage of
using MIMO techniques, we used a single input multiple output (SIMO)
system as a baseline for performance comparison. The gain mechanisms
of the MIMO system over the SIMO system are investigated and their
characteristic at different traffic load conditions are highlighted.
The simulation results are used to verified our proposed model to
predict the performance of the SIMO and MIMO systems in a bursty
traffic network.
