Under contract with the U.S. Air Force, Radix developed a system for covert, jam-resistant communications using blindly-adapted receiver arrays and directive transmit beamformers.

Some features of this technology include:

• Supports point-to-point and point-to-multi-point applications
• Flexible, modular spread spectrum waveform coupled with adaptive beamforming
• A combination of stacked carrier and OFDM provide a flexible, multi-path tolerant waveform with high spectral efficiency
• Frequency reuse of 1
• Packetized data transmission
• Operates in the presence of interference
  

This robust, high-efficiency communications airlink led to a collaboration between Radix and a large telecommunications company on a fixed wireless application. This technology can also be adapted to emerging battlefield communications requirements, as well as other commercial wireless applications.
