Radio frequency (RF) all-digital transmitter (ADT) is one of the most attractive techniques in the next-generation RF transceivers, especially in the carrier aggregation and multiband, multistandard ...

This paper proposes a novel resonator structure for efficiency and transferred power improvements: a transmitter (a receiver) that consists of two strongly coupled resonators. The two strongly coupled ...

Different participants performing activities, the location of the RF transmitter/receiver, and the exact location of the performed activity in an indoor environment affect localization and HAR.
