Pdf Energy Efficient Hybrid Analog And Digital Precoding For Mmwave This paper addresses the suboptimal energy efficiency of conventional digital precoding schemes in multiple input multiple output (mimo) systems. through an analysis of the power amplifier (pa) out. These findings highlight the potential of cnn based hybrid precoding to revolutionize thz communication in next generation wireless networks by optimizing energy efficiency and system complexity. Modern day millimeter wave communication systems prefer hybrid precoding architecture over digital architecture due to higher energy efficiency, lower power consumption and comparable spectral efficiency. Here, for the first time, we apply the emerging analog matrix computing (amc) to the linear precoding of massive mimo. the real valued amc concept is extended to process complex valued signals. To efficiently determine the required number of active rf chains, we characterize spectral and energy efficiencies of the mmwave mimo channel with closed form expressions in both static and mobile communication channels. Abstract: in mimo systems, hybrid digital and analog precoding structures are gaining attention for reducing power consumption and costs compared to fully digital precoding. however, deployment expenses and circuit power consumption still pose challenges.
