Performance Evaluation of Variable xASK-CodeSK Scheme

Abstract

Recently, sensor devices have been spreading rapidly owing to the development of the internet of things (IoT). They are often battery-driven and therefore have limited energy capacity. To extend the operating time while maintaining the communication function, simultaneous lightwave information and power transfer (SLIPT) is in demand. The aim of this paper is to evaluate the bit success rate (BSR) and power transfer rate (PTR) of Variable xASK-CodeSK by using theoretical formulas. The results indicate that there is a tradeoff relationship between BSR and PTR. Moreover, it is found that there is an optimal value of x for optimizing the tradeoff relationship.
