Directional modulation (DM) has emerged as a highly promising physical layer security technique that embeds confidential information into the spatial characteristics of the transmitted signal. By ...

RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

Swept spectrum analyzers can't keep pace with today's RF signals. Gathering RF signal information using realtime approaches is better, but even that is only a beginning. The strength of realtime RF ...
