Throughput Optimization Via Adaptive MIMO Communications

Abstract

A MIMO-OFDM system for aircraft to urban ground non-line-of-sight communications that supports programmable bandwidth efficiency between 0.25 bps/Hz and 20 bps/Hz has been designed. The system supports the whole range of MIMO techniques, namely spatial multiplexing, beamforming, space-time coding, and diversity processing. The system is, on a packet by packet basis, configurable in terms of number of antennas, MIMO techniques, modulation order, channel coding type, channel coding rate, channel training length, and channel tracking overhead. The feasibility and performance has been verified in the developed Matlab end-to-end simulation system and on the Silvus DSP MIMO Testbed.
