1. A roving communication system comprising:
- a roving electronics system configured to wirelessly link communications between a foreground region and a background region, the roving electronics system being onboard at least one platform having background antennas and being set up to link communications generated using wave front multiplexing techniques and comprising a ranking system to rank the communications;
wherein the ranking system comprises adjusters of beam positions of the background antennas for communications between the background region and the roving electronics system;
wherein the ranking system is based on an index of a likelihood of an arrival of a desired signal from different possible beam positions within a time frame of a diagnostic cycle;
wherein the wave front multiplexing techniques are configured to multiplex first signals received from the background region by the roving electronics system; and
wherein the wave front multiplexing techniques are configured to multiplex second signals received from the foreground region by the roving electronics system.

Abstract
Aircrafts flying near Earth or naval vessels are used as communications towers or relays. Using techniques of ground based beam forming and wavefront multiplexing enhance the ability to coherently combine the power of the communication signals, and improve the signal-to-noise ratio. When multiple antennas or signal sources exist, a ranking system is employed to optimize performance.
