Discrete Spectrum Techniques for Spectral Regrowth Analysis News & Analysis 3/14/2002 Post a comment You can use discrete-spectrum signal representation to analyze distortion due to spectral regrowth in nonlinear devices, such as those found in wireless-communications systems. However, this technique introduces errors in both output bandwidth and power estimation of the spectral regrowth. Torben Larsen of Aalborg University, Denmark, shows how the bandwidth error may be large, but is predictable.
Efficient Near-Field to Far-Field Transformation Techniques for Antenna Measurements Design How-To 3/1/2002 Post a comment Fernando Las-Heras of the Universidad Politcnica de Madrid, Ciudad Universitaria, and T.K. Sarkar of Syracuse University propose a new technique for Near-Field to Far-Field transformation for antenna measurements, using an equivalent current representation with a matrix-method solution. With this technique, the authors have obtained accuracy comparable to standard wave transformation methods.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
