Energy Beamforming with One-Bit Feedback - arXiv

WebThe use of single-bit modulators, rather than multi-bit A/D converters, can greatly reduce the electronics inside a beamformer [1], [2]. In recent years, receive beamforming using single-bit modulation has received significant attention. In [2]-[5], system level architectures are proposed, analyzed, and simulated for single-bit beamformers. Web29. jun 2024. · The increased power consumption of high-resolution data converters at higher carrier frequencies and larger bandwidths is becoming a bottleneck for communication systems.
