Digital mobile battlefield environments impose challenging obstacles to battle group communications and data management. As future communication capabilities cascade from tactical commanders to individual soldiers, increased spectral clutter will complicate the task of preserving data throughput. Applied within a programmable radio architecture, frequency hop (FH) and direct sequence (DS) waveforms have inherent strengths that may be exploited to overcome battlefield communication obstacles. In this paper, we present a methodology that combines the FH waveform with pulse concealment and transform domain signal processing in order to overcome interference, hostile detection, and jamming. Rejection algorithms are demonstrated which significantly improve system performance in the presence of high-power partial-band jammers, co-site communication signals, and fading
