Wideband Radio Local Interference Optimization Techniques
Today"s military operations depend on reliable voice and data communications all the way to the tactical edge, including between individual dismounted infantrymen. Competing wireless services, self-protection electronic countermeasures (CREW), and hostile jamming can saturate the spectrum and impair essential communications. Adaptive Dynamics, Inc. has developed the novel Multiple Adaptive Generalized Interference Cancellation (MAGICTM) filter, which has demonstrated remarkable performance for protecting narrowband UHF communications by separating out multiple overpowering interfering signals while preserving the desired communications signal. This technique has been further developed and demonstrated with high fidelity simulations to be effective when applied to wideband waveforms, potentially mitigating interference levels in excess of 80dB above the desired signal. In the proposed work, Adaptive Dynamics will develop enhancements to the MAGICTM filter applicable to the Soldier Radio Waveform (SRW), optimize the algorithm as a VHDL core for insertion into the baseband processing chain of an ITT Exelis Soldier Radio-Rifleman (SR-R), and perform field testing in a tactical electro-magnetic interference (EMI) environment.
