Abstract

Current omnidirectional jam-resistant technology
relies on shared secrets. This forces private networks
to exchange keys before jamming is present and leaves
public networks (like GPS or ADSB/Mode-S) unprotected.
Given the proliferation of inexpensive Software Defined
Radios (SDRs), robust jam-resistant options are more
important than ever. This project implements the “BBC”
codec–a keyless, concurrent codes spread-spectrum (CCSS)
strategy–in GNU Radio. Initial testing of the BBC codec
confirms theoretical performance estimates and suggests
that BBC is a viable option to preserve information
availability. Development is underway to provide an out-oftree
(OOT) module for broader use within the GNU Radio
community.
