Beamspace Multiple Input Multiple Output. Part II: Steerable Antennas in Mobile Ad Hoc Networks
Abstract
This report finds that steerable antennas may dramatically increase the signal-to-interference-and-noise ratio (SINR) at a receiver in a mobile ad hoc network (MANET). If all radios in a MANET have steerable antennas and a method of distinguishing a desired signal from interference, simulations and experimental data suggest most radios would experience a significant SINR increase, and consequently, a throughput increase. Simulations of eight radios showed roughly a doubling in throughput by using steerable antennas. The report first documents the Beamspace multiple-input multiple-output (MIMO) transmission and reception methods following the work done in a 2015 Space and Naval Warfare Systems Center Pacific technical report. Then, it shows that the method for emulating a transmit array of separate antennas is highly unlikely to work for the higher-order modulations that are required for MIMO. Next, the report details the potential throughput increase if antennas in MANETs would optimally steer their beams, through both simulation and over-the-air experiments. Then, a design for a compact electronically steerable parasitic array radiator (ESPAR) and control board is given along with antenna measurements. Finally, the report concludes with future ideas toward creating a bolt-on layer compatible with radios currently in service.
