Large-scale multiple-antenna systems with large bandwidth are fundamental for future wireless communications, where the base station employs a large antenna array.In this scenario, one problem faced is the large energy consumption as the number of receive antennas scales up.Recently, low-resolution analog-to-digital converters (ADCs) have attracted

The principle of hybrid information hiding represented by process of information hiding message (multimedia files) embedded inside another message which is depended on hiding a certain media in another media using different domains (special domain, frequency domain) to provide protection and security for transformed data, this paper suggest an algo

Ejector refrigeration systems are rapidly evolving and are poised to become one of the most preferred cooling systems in the near future.CO2 transcritical refrigeration systems have inherently high working pressures and discharge temperatures, providing a large volumetric heating capacity.In the current research, the heat ejected from the CO2 gas c
