The present invention employs a novel use of multiplexing and cross-connect architecture to improve energy efficiency in optical networks.

The invention describes a small, light-weight, low-power, multichannel radio that receives signals from ground based commercially-licensed broadcast transmitters and analyzes these signals to estimate the receiver's position, groundspeed and heading. Other technologies providing navigation data from ground-based RF broadcasters require a local ground based reference station.
Development status: completed system-level simulation; awaiting experimental proof-of-concept

This invention provides a computationally efficient means of performing adaptive pulse compression (APC) and is denoted as the Fast APC (FAPC) algorithm. The FAPC algorithm dramatically reduces range sidelobes while maintaining near optimal signal-to-noise (SNR) gain and is much more computationally efficient than the original APC.
