Abstract: The dynamic range (DR) of digital-input closed-loop class-D amplifiers (CDAs) is typically limited by the noise introduced by their resistive DAC (RDAC) or current-steering DAC (IDAC). It ...
Abstract: This paper presents an efficient channel estimation algorithm for multi-user reconfigurable intelligent surface (RIS)-aided millimeter-wave (mmWave) systems. In this paper, the concept of ...
