LabVIEW based modeling of SWIPT system using BPSK modulation

Abstract

This paper presents a simultaneous wireless information and power transfer (SWIPT) system modeling in LabVIEW. Since SWIPT system is very active research topic, a complete system level modeling is indispensable. The LabVIEW based modeling of SWIPT system facilitate the research by providing the system level simulation in an efficient and comprehensive way. Both the SWIPT transmitter and receiver are modeled in LabVIEW environment. The SWIPT transmitter modulates digital data and up-convert to RF carrier frequency at 1 GHz. At SWPIT receiver, RF energy is harvested through RF rectifier in energy harvesting (EH) path. Simultaneously, digital information is recovered through information decoding (ID) path. The BPSK modulation is used for data transfer in SWIPT system. Presented modeling utilizes powerful system design capabilities of LabVIEW which assists in the development and testing of SWIPT system.
