Abstract

This paper presents a set of rigorous and comprehensive coverage and throughput studies for enhanced high-capacity Multi-Input Multi-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems. A ray-tracing propagation model has been used to produce site-specific MIMO channel data. Site-specific throughputs are then predicted in a city centre environment for a range of different physical layer configurations. Dynamic Transmit Power Control (TPC) is applied to lower transmit power and thus reduce interference. Results demonstrate the need for suitable link adaptation strategies under a wide range of channel conditions. Spatial Multiplexing (SM) is shown to struggle in regions close to the basestation, or for locations with low SNR. We conclude that it is vital to reconfigure parameters on a case by case basis. When a suitable space-time algorithm is combined with Adaptive Modulation and Coding (AMC) and the appropriate number of antenna elements, high peak throughputs and good geographic coverage become realistic for wireless applications in a dense urban environment.
