Companding and Predistortion Techniques for Improved Efficiency and Performance in SWIPT

IEEE Transactions on Green Communications and Networking
In this work, we analyze how the use of companding techniques, together with digital predistortion (DPD), can be leveraged to improve system efficiency and performance in simultaneous wireless information and power transfer (SWIPT) systems based on power splitting.
