DeepDeMod: BPSK Demodulation Using Deep Learning Over Software-Defined Radio

IEEE Access, 2022
In wireless communication, signal demodulation under non-ideal conditions is one of the important research topic. In this paper, a novel non-coherent binary phase shift keying demodulator based on deep neural network, namely DeepDeMod, is proposed.

A novel clustering-based filter for impulsive noise reduction in electromagnetic tomography (EMT)

AIP Advances, 2020
Demodulation is a crucial step in signal processing for electromagnetic tomography (EMT) systems. Impulse noise appears in EMT, in particular, when excitation current is switched from one coil to another.

Digital Demodulation of Interferometric Signals [PDF]

, 2012
The marriage of optical sensing techniques with sophisticated digital signal processing has resulted in a myriad of practical metrology systems. Optical metrology systems offer many attractive measurement features. These systems are inherently non-contacting, nondestructive, and immune from electromagnetic interference. In addition, since light is used

Metasurface‐Enabled Active‐Like Passive Radar

Advanced Science, EarlyView.
A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

Digital Demodulator of the Quadrature Amplitude Modulation Signals [PDF]

Measurement Science Review, 2018
Abstract In this paper, the digital algorithm and the device for the demodulation of the quadrature amplitude modulation signals are considered. The fundamental advantages of our approach are simple hardware implementation, minimal number of arithmetic operations required over the signal period as well as the potential interference ...

Hadamard Matrix Slicing Single‐Pixel Imaging: Establishing a Linear‐Array‐Inspired Paradigm for N‐fold Acceleration Single‐Pixel Imaging

Advanced Science, EarlyView.
To overcome two‐dimensional modulation bottlenecks, Hadamard Matrix Slicing Single‐Pixel Imaging (HMS‐SPI) establishes an efficient one‐dimensional imaging paradigm. By slicing the traditional Hadamard matrix into one‐dimensional encoding vectors and spatially expanding them, the required measurement patterns decrease by a factor of N.

Interference Aspects of Adaptive Modems over Slow Rayleigh Fading Channels [PDF]

, 1999
Adaptive modulation can achieve channel capacity gains by adapting the number of bits per transmission symbol on a burst-by-burst basis, in harmony with channel quality fluctuations. This is demonstrated in the paper for target bit error rates of 1 and 0.
