Spectrum Agile Network Distributed Subcarrier Allocation

Shared Spectrum Company (SSC) and Boeing Integrated Defense Systems build on their work on the JTRS GMR, DARPA MAINGATE, EPLRS and XG programs to incorporate spectrum agile, network, distributed, subcarrier allocation radio capabilities into the Joint Tactical Radio System GMR Wideband Networking Waveform (WNW). The purpose of this project is to define candidate space-time-frequency distributed algorithms and protocols for the physical, MAC, and network layers in a network for manipulating the spectra of OFDM wireless networks nodes in response to degradations observed geographically within the network and within its spectrum. Our approach considers multiple factors (non-cooperatives (Dynamic Spectrum Access - DSA), resource allocation, multi-path interference and interference mitigation to influence subcarrier selection. Our design in based on its DSA software with dynamic subcarrier allocation that has already been ported to two different radio platforms (MAINGATE and EPLRS). Boeing provides detailed knowledge of the WNW waveform and WNW software architecture.
