Downlink throughput statistics in interference-limited cellular systems with multi-element antennas

In this study, we first quantify cell-wide mean throughputs in interference-limited single-input-single-output (SISO) and multi-element antenna (MEA) cellular systems along various system-level design dimensions, including: MEA array size; frequency-reuse factor; antenna pattern (omni-directional or sectorized); degree of coding; allowable constellation size; and transmitor receive-adaptation. Next, we examine the validity of a noise-model for co-channel interference present in MEA links. Using system simulations, we show that this model is valid under all conditions, with varying levels of accuracy.
