Radar Signal Recognition Based on CSRDNN Network

open access: yesIEEE Access
It is essential to achieve the high-accuracy recognition of low probability of intercept (LPI) radar signals in modern electronic warfare. However, under low signal-to-noise ratio (SNR), the recognition accuracy of the LPI radar signals is relatively low.

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 ...
