Low Probability of Intercept Waveforms via Intersymbol Dither Performance under Multipath Conditions [PDF]

open access: yes, 2009
This thesis examines the effects of multipath interference on Low Probability of Intercept (LPI) waveforms generated using intersymbol dither. LPI waveforms are designed to be difficult for non-cooperative receivers to detect and manipulate, and have ...

A Real Orthogonal Space-Time Coded UWB Scheme for Wireless Secure Communications

open access: yesEURASIP Journal on Wireless Communications and Networking, 2009
Recent research reveals that information security and information-hiding capabilities can be enhanced by proper exploitation of space-time techniques. Meanwhile, intrinsic properties of ultra-wideband (UWB) signals make it an outstanding candidate for ...
