The effects of multipath propagation lead to a significant decrease in system performance in most of the proposed ultra-wideband communication systems.A time-reversed system utilises the multipath channel impulse response to decrease receiver complexity, through a BETA ALANINE prefiltering at the transmitter.This paper discusses the modelling and c
Wireless and power line communication hybrid relay technology can realize complementary advantages and comprehensively improve the communication coverage and performance of power Internet of Things.In order to study the mechanism of the physical layer and Media Access Control (MAC) layer algorithm that affects the performance of hybrid relay system
The Hatchets introductory essay frames the monographic section of this volume, which investigates the theme of the challenges that face education in situations of conflict and division in the contemporary world.Armed conflict has caused devastation in the past year in Ukraine and, over a longer period of time, in other parts of the world, notably A
