Performance Analysis of SWIPT Assisted NO-DLT ISAC Systems

This paper investigates the performance of simultaneous wireless information and power transfer (SWIPT) non-orthogonal downlink transmission integrated sensing and communication (ISAC) system. Particularly, residual hardware impairments, channel estimation errors, and imperfect successive interference cancelation are taken into account. The expressions of exact and asymptotic outage probabilities, probability of detection (PoD), and energy efficiency (EE) are derived for communication and sensing (C&S) performance evaluation. The simulation results verify the accuracy of our theoretical analysis and reveal that the introduce of SWIPT into ISAC system can improve both C&S performance in terms of fairness, PoD as well as EE.
