Abstract: The digital switch-capacitor power amplifier (SCPA) suffers from the harmonics distortion which results in degraded out-of-band (OOB) suppression and the communication quality. This paper ...
Abstract: A direction-of-arrival (DOA) estimation approach for multiple incident signals is proposed based on space-timecoding (STC) digital metasurfaces. The STC metasurface modulates the incident ...
