#ENAMS – Why is it needed? International treaties bind nations to use spectrum according to the ITU- regulations * EMI-Certification Measurements – emissions of devices are certified ● 0-30 MHz: conducted line emission measurements but no radiated noise (laboratory size < wavelength) ● Technology of power devices changed over past 50 years ● Increasing number of power electronic devices without certification ● Fast switching power electronics in solar converters and optimizers Solution: * Collect arguments against radiated radio noise below 30 MHz via CyRComms

Paper is presented at the international conference 11th International Conference on Electrical, Electronic and Computing Engineering G. T. Djordjevic, N. Milosevic, M. Petkovic, B. Vasic, D. Milic, B. Vasic, “A Numerical Method for Estimating Error Rate Performance of MPSK System influenced by Fisher-Snedecor Fading”, 2024 11th International Conference on Electrical, Electronic and Computing Engineering, pp. 1-5, Nis, Serbia, June 3-6, 2024. The aim of this paper is to estimate the error probability in coherent detection of multilevel phase-shift keying (MPSK) signals transmitted through a channel in which the multipath fading and shadowing are present simultaneously together with thermal noise. To describe this type of fading, we use a Fisher-Snedecor model that was proposed relatively recently. For this fading model, using the Fourier series, we first represent the probability density function (PDF) of the composite signal phase. We present expressions for the coefficients in the Fourier series, that were previously derived by ourselves. We examine the convergence of this series for different numerical values of the channel parameters. Next, we present the expression for estimating the error probability in MPSK signal detection. Based on this, we examine the influence of multipath fading severity and the shadowing spread on the numerical values of the error probability for different number of phase levels. The obtained results enable a further evaluation of the performance of differentially coded signals, as well as an evaluation of the influence of the phase noise both on the error probability and the mutual information in the channel with this type of fading.

Nearly 800 attendees from around the globe gathered at the AT&T Center in Austin, Texas, for the 57th Institute of Electrical and Electronics Engineers Association for Computing Machinery International Symposium on Microarchitecture. As the premier conference for computer architecture research, the event brought together researchers and luminaries to discuss the latest advances in the field. The conference set records for attendance, paper submissions and workshops. Researchers representing 132 universities, national laboratories and companies showcased their latest work. Dr. Paul Gratz, a #TAMUecen professor who served as the general co-chair, and Dr. Daniel A. Jiménez, a professor in the Department of Computer Science and Engineering who served as program co-chair, spearheaded the event from Texas A&M University. Read more: tx.ag/Microarchitecture

https://lnkd.in/ebRgN3X3 An introduction to several fundamental ideas in electrical engineering and computer science, using digital communication systems as the vehicle.

The final evaluation conducted yesterday marked the completion of the Project Work course. This journey has been an enriching learning experience, characterized by the persistent dedication of all team members—Juho, Jon, Petri and me—and the excellent guidance provided by our instructors, Rayane Mourouvin and Tuure Nurminen. The primary objective of the project has been to develop a small-scale, low-voltage test setup for evaluating the parallel operation of grid-connected converters. Suitable grid-following (GFL) and grid-forming (GFM) control methods were deployed to the setup and ran under different grid scenarios. Experimental results were obtained, showcasing the characteristics of different control methods during connection to an existing grid, power reference tracking, islanded mode operation, and common grid faults such as grid voltage drops and frequency fluctuations.
