The information-carrying programmable metasurfaces have found widespread applications in communication, sensing, and other related areas. However, there is a fundamental but unresolved problem,i.e., the rigorous understanding of the quantization of metasurface coding. Here, we theoretically investigate the...
Presents a study which proposed a method for improving the signal-to-noise ratio (SNR) of sigma-delta modulators with one-bit quantization. Features of sigma-delta modulation; Basic concept of adaptive sigma-delta modulation; Slew-rate limitation of the input signal; Signal reconstruction from sequ...
(1) 1-bit quantization. 用Wfine和Wbase分别表示微调后模型的权重和base模型的权重, 最终的目标是希望压缩delta,即希望把delta表示为系数*1bit值的形式, 量化后的表示形式如下: 为了去缩小量化前后的误差,这里取权重矩阵的均值作为系数,实验证明这种取值方法已经能够达到一个比较好的效果。
direction of arrival; one-bit quantization; noise-boosted quantizer unit; multiple-signal classification 1. Introduction Direction-of-arrival (DOA) estimation [1,2,3,4,5,6] has attracted considerable attention in the field of array signal processing, and its applications to wireless communications,...
Time compression system adding noise to allow one bit quantizationA time compression signal processor which adds noise in a signal-free region and samples at such a rate that the noise does not interfere with the signal region, comprising a filter, noise generator and summer for adding noise to...
A one-bit digital over-the-air aggregation (OBDA) scheme has been recently proposed, featuring one-bit gradient quantization at edge devices and majority-voting based decoding at the edge server. However, the low-resolution one-bit gradient quantization slows down the model convergence and leads ...
