Noise Shaping Enhanced DMT Signal Transmission Utilizing Low-Resolution DAC
IEEE Photonics Journal, 2021 In order to reduce the quantization noise of low-resolution DAC, we study a noise shaping technique that can reshape the white quantization noise to an irregular spectrum, in which the noise in the data subcarrier band is almost transformed into the null

Journal of Physics: Conference Series, 2021 Abstract Quantization is one of the most popular and widely used methods of speeding up a neural network. At the moment, the standard is 8-bit uniform quantization. Nevertheless, the use of uniform low-bit quantization (4- and 6-bit quantization) has significant advantages in speed and resource requirements for inference.

Известия высших учебных заведений России: Радиоэлектроника, 2021 Introduction. The digital representation of received radar signals has provided a wide range of opportunities for their processing. However, the used hardware and software impose some limits on the number of bits and sampling rate of the signal at all ...

A fourth‐order incremental ADC in three‐step
The Journal of Engineering, 2021 This letter presents a second‐order incremental ADC (IADC) operated in three steps, which extends the performance of a second‐order IADC close to that of a fourth‐order IADC with only two amplifiers.

On general lattice quantization noise [PDF]
2008 IEEE International Symposium on Information Theory, 2008 The problem of constructing lattices such that their quantization noise approaches a desired distribution is studied. It is shown that asymptotically is the dimension, lattice quantization noise can approach a broad family of distribution functions with independent and identically distributed components.

Spectral Efficiency of One-Bit Sigma-Delta Massive MIMO [PDF]
, 2020 We examine the uplink spectral efficiency of a massive MIMO base station employing a one-bit Sigma-Delta ( \Sigma \Delta ) sampling scheme implemented in the spatial rather than the temporal domain.

Applied Sciences, 2023 In this paper, we analyze the performance of a full-duplex (FD) cooperative non-orthogonal multiple access (C-NOMA) relaying system with an amplify-and-forward (AF) protocol in the presence of loopback interference in FD transceivers.

Variational Bayesian algorithm for quantized compressed sensing [PDF]
, 2013 Compressed sensing (CS) is on recovery of high dimensional signals from their low dimensional linear measurements under a sparsity prior and digital quantization of the measurement data is inevitable in practical implementation of CS algorithms.
