A method of increasing reliability of a wireless radio includes: creating a first waveform at a first center frequency of an encoded data stream using a first wireless radio; creating a second waveform at a second center frequency of the encoded data stream using the first wireless radio; combining the first waveform and the second waveform into a composite waveform with redundant data streams at different center frequencies using the first wireless radio; wirelessly transmitting the composite waveform using the first wireless radio; wirelessly receiving the composite waveform; filtering the received composite waveform using a first filter band; digitizing the received composite waveform using the second wireless radio; demodulating the digitized composite waveform into a first data stream and a second data stream with the second wireless radio; and creating a third data stream representative of the encoded data stream.

Quad band relay Common Data Link system and method

A method for finding an orthogonal direction of a radiation source with respect a digitally optimized interference pattern of a first fixed electromagnetic element and a second fixed electromagnetic element has been established. Determining a direction of a radiation source allows for dynamic control of moving object.

System and method for digital direction finding

A method of creating a dynamically sharp location based filter includes: placing a moving object containing two or more antennas used for direction finding of a radiation source within a anechoic testing chamber; moving one or more radio transmitters within the anechoic chamber relative to a future spatial location, angle, and/or position of the moving object over a defined time; record an expected angle of arrival of one or more signals of the one or more radio transmitters with respect to the future spatial location, angle, and/or position of the moving object over the defined time; and program a filter within the moving object based on the recorded expected angle of arrival of the one or more signals.

System and method for creation of a dynamically sharp filter

A system and method of improving data link performance between two or more wireless data transceivers includes: clipping and inverting the data components of a communication signal which are calculated to cause non-linear saturation effects in the downstream power amplifier; delaying a first time series to align the first time series with the clipped and inverted data components of a second time series; adding the clipped and inverted data components of the second time series to the delayed first time series to obtain a modified composite waveform; creating a sacrificial band containing principal energy of the clipped and inverted data components of the second time series; harvesting the principal energy of the sacrificial band to obtain an optimized composite waveform; and amplifying the optimized composite waveform with the downstream power amplifier of one or more of the two or more wireless data transceivers.

A filter can include a first channel and a second channel. The first channel can be configured to process a first term and a second term of an input vector using a first coefficient and a second coefficient of the filter. The first channel can be configured to generate a first term of an output vector. The second channel can be configured to process the first term and the second term of the input vector using the first coefficient and the second coefficient of the filter. The second channel can be configured to generate a second term of the output vector. The first and second channels can be configured to operate in parallel.
