Web10. apr 2024. · By embedding each sensor into a reconfigurable intelligent surface (RIS) controller, in this letter we propose an efficient RIS-based wireless sensor network (WSN) for simultaneous passive beamforming and decision gathering. In RIS-WSN, the reflection amplitudes and phase shifts of RISs are designed to convey the local decisions made by … WebOne solution is to use a low-resolution ADC to replace the full-precision ADC. In this paper, we propose a mixed LMS (Least Mean Square) receiver beamforming method for a …

WebThis can also be combined with hybrid beamforming.Some of these evaluations consider only the extreme case of 1-bit quan-tization [8], [12], [5], [13]. In [14], [15] the Analog/Digital (A/D) conversion is modeled as a linear stochastic process. Low resolution A/D conversion combined with Orthogonal Frequency Domain Multiplexing (OFDM) in an ... Webprovides full access to each element. Despite these advantages, digital beamforming has been limited by high power consumption, large die area, and the need for large numbers of analog-to-digital converters. Furthermore, beam squinting errors and ADC non-linearity limit the use of large digital beamforming arrays. We address these limitations. food safety and hygiene definition
