We consider the problem of jamming in non-coherent wideband fading channels. While the problem is well understood for coherent channels, the results for the coherent case do not generalize in the non-coherent regime. We show that energy-limited jammers do not affect capacity in the wideband regime. We also propose a training based transmission scheme that is able to achieve the wideband limit in the...
We investigate the fundamental limits on communication performance in wideband fading channels, in the presence of a jammer. We show that energy-limited Gaussian jammers cannot affect the error exponents in the wideband regime. However, if the sender uses an impulsive training scheme, which is close to optimum in the wideband regime, the jammer may be able to interfere with sounding signals if the...
