A radio signal reception technique includes selecting a sample rate from a plurality of predefined sample rates so that the radio signal is contained entirely within a Nyquist zone corresponding to the sample rate. The radio signal is passed through a selected one of a plurality of selectable bandpass filters to provide an analog signal. The analog signal is sampled at the sample rate and converted to a digital signal.

A spectral sensing demodulator can include a programmable filter bank and a reconfigurable processor coupled to the programmable filter bank. The programmable filter bank can frequency demultiplex a plurality of frequency division multiplexed channels from a frequency band into a plurality of demultiplexed channels. The reconfigurable processor can include a plurality of reconfigurable resources. Each resource can be alternatively be configured to demodulate a demultiplexed channel and to monitor a demultiplexed channel.

Wireless terminals, systems, and methods use interlaced diplexers. A first diplexer can provide a first pair of bands separated by a first separation band, and a second diplexer can provide a second pair of bands separated by a second separation band. The first separation band and the second separation band can overlap. Transceivers (comprising transmitters and receivers) can be coupled to the diplexers to provide frequency-division duplex communications using one or both of the pairs of bands.

The present invention relates to a towed wireless network communications subsystem for use in flight by a towing aircraft. The towed wireless network communications subsystem includes an aerodynamic enclosure having a tether attachment and configured to be towed by the towing aircraft. A directional antenna is disposed on the aerodynamic enclosure and is capable of forming one or more directional communications beams within a wireless network. A communications device is disposed in the aerodynamic enclosure and is coupled to the directional antenna(s). The communications device is configured to relay communications data between the towing aircraft and the wireless network.
