TLDR
This paper presents a methodology that combines the FH waveform with pulse concealment and transform domain signal processing in order to overcome interference, hostile detection, and jamming.Abstract:
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.read more

Narrow-band interference rejection using transform domain signal processing in a hybrid DS/FH spread-spectrum system
TL;DR: The performance of a narrow-band interference rejection scheme using transform domain signal processing is studied in a hybrid DS/FH spread-spectrum system and the criterion for the evaluation of the performance of the interference rejection algorithm is the bit error probability as a function of E/sub b//N/sub 0/ and signal to jammer ratio.
