Analog Video Encoding and Quality Evaluation
(M D P I AG, 2019-07-23)
[Abstract] The most widespread analog video encoding systems in the literature are based on the use of the 2D and 3D DCT. These systems use both transformations indistinctly without assessing their suitability. In this ...
Numerical Model of a 28-GHz Frequency Diverse Array Antenna
(MDPI AG, 2020-08-22)
[Abstract] In this work we make use of the frequency diverse array (FDA) concept, whose design is based upon a frequency increment across the antenna elements to generate a beam steering that is a function of angle, time ...
