Error correcting coding scheme against partial time jammers

Abstract

This paper proposes a new approach to antijamming against high energy partial time jammers concerning applications where the usual scheme sprectrum spreading + error correcting coding is not efficient because of the small value of the spreading gain, due to the channel bandwith limitation and to the minimum data rate required on the link. It consists in exploiting the short duration of the jamming pulses and trying to reconstitute the erased information by means of error correcting codes. An efficient coding scheme and a new method of erasure localization are proposed.
