Energy Harvesting and Optimization Using Broadcast Channel Approach for MIMO Systems in Wireless Sensor Networks

Abstract

EM or radio signal enabled WPT in particular. Since radio signals can carry power and information simultaneously, simultaneous data transmission and power transmission (SWIPT). A three-point wireless transmission system (MIMO), in which one receiver harvests power and the other receiver determines the data separately from the signals sent by the standard transmitter, and all transmitters and receivers probably have multiple antennas. Two scenarios are tested, in which the information receiver and the power receiver are separated and detect different MIMO channels from the transmitter, or which are collectively available and detect the same MIMO channel from the transmitter. In the case of split receivers, we find an appropriate transfer strategy to achieve various tradeoffs with a higher amount of data compared to a power transfer, which is reflected by a regional boundary rate-rate (R-E). In the case of co-acquisition recipients, we indicate the external boundary of the accessible R-E region due to the potential limit that power harvest recipients are not yet able to determine the exact details. Under this barrier, it investigates two cohesively formed cases, namely time shifts and power divisions, and then shows their accessible R-E regions in relation to the external boundary.
