Application of LTE small cells in urban environments for higher capacity

Extending conventional LTE systems with small cells offer new horizon in mobile communications to provide better coverage and enhance capacity. OFDM-based air interfaces allow sharing this capacity in a very flexible way. MIMO transmitters and receivers introduce significant increase in capacity in exchange of very sophisticated signal processing algorithms. In this paper we present a new system model for OFDM-based LTE small cell systems which allows computing the overall system capacity when mobile MIMO users move along edges of a graph, e. g. roads.
