Deep Learning-Aided Modulation Recognition for Non-Orthogonal Signals [PDF]

open access: yesSensors, 2023
Automatic Modulation Recognition (AMR) can obtain the modulation mode of the received signal for subsequent processing without the assistance of the transmitter. Although the existing AMR methods have been mature for the orthogonal signals, these methods

Coexistence of Orthogonal and Non-orthogonal Multicarrier Signals in Beyond 5G Scenarios [PDF]

open access: yes2020 2nd 6G Wireless Summit (6G SUMMIT), 2020
Optimum operation of future mobile communication systems requires more flexible signalling mechanisms for radio access. For flexible heterogeneous signalling implementation, this work discusses coexistence scenarios of orthogonal and nonorthogonal multicarrier signals, specifically considering orthogonal frequency division multiplexing (OFDM) and ...

Harmful intrusion detection algorithm of optical fiber pre-warning system based on correlation of orthogonal polarization signals

open access: yesPhotonic Sensors, 2017
At present, advanced researches of optical fiber intrusion measurement are based on the constant false alarm rate (CFAR) algorithm. Although these conventional methods overcome the interference of non-stationary random signals, there are still a large ...

Analysis of orthogonal signal of dual-mass micro-machined gyroscope [PDF]

open access: yesMATEC Web of Conferences, 2022
The dual-mass Silicon micro-machined gyroscope was processed by micro-fabrication technology. It could lead to quadrature coupling error and influence the output of the silicon micro-gyroscope. We select two commonly used gyroscope structures and analyze

Three‐phase algorithm for independent single‐phase grid frequency estimation under grid disturbances

open access: yesIET Generation, Transmission & Distribution, 2023
This paper reports an algorithm for quick and precise estimation of the single‐phase grid frequency under DC offset and both odd and even harmonics. The proposed single‐phase grid frequency estimation method is derived from a three‐phase relation.

Orthogonal Signal Generation: An Analytical Approach

open access: yesCircuits, Systems, and Signal Processing, 2023
Nowadays, many signal processing activities are related to the orthogonal properties of specific signals. However, only a few methods offer an analytical solution for generating orthogonal signals, especially when only one input to the generating system is available. These methods are often related to very specific applications and lack generalization.
