On the Performance of Spectrally-Encoded Spread-Time Ultrawideband CDMA Communication Systems
In this paper we study the performance of Spectrally-Encoded Spread-Time (SE/ST) technique when applied to ultrawideband (UWB) signals in the context of wireless code-division mult...

Adaptive Jamming-Resistant Broadcast Systems with Partial Channel Sharing
—Wireless communication is particularly vulnerable to signal jamming attacks. Spread spectrum mitigates such problem by spreading normal narrowband signals over a much wider band...
