This paper presents a review of proposed algorithms for power system frequency and amplitude tracking based on sample comparison, Clarke transformation, Zero-Crossings (ZC), Discrete Fourier Transformation (DFT), Gauss-Newton (GN) search, and Maximum Likelihood (ML) concepts. The aim is to identify their performance, strengths and weaknesses, under present power system conditions, proposing some improvements,...
This paper reports a measurement campaign carried out at 3.5 GHz to characterize the outdoor to indoor electromagnetic (EM) wave propagation penetration within buildings. A wideband channel sounder was used to collect the data using circular antenna arrays at both ends. The measurements are processed with a high resolution algorithm extracting the dominant paths. A ray-tracing based simulation tool...
