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

Underdetermined Blind Source Separation of Synchronous Orthogonal Frequency Hopping Signals Based on Single Source Points Detection

open access: yesSensors, 2017
This paper considers the complex-valued mixing matrix estimation and direction-of-arrival (DOA) estimation of synchronous orthogonal frequency hopping (FH) signals in the underdetermined blind source separation (UBSS).

Feedback communication using orthogonal signals [PDF]

open access: yesIEEE Transactions on Information Theory, 1969
We consider a feedback communication system in which the forward and feedback channels are disturbed by additive noise and constrained in average power. Two block coding schemes are proposed in which the signals are orthogonal waveforms. A finite number of forward and feedback transmissions per message is made.

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

Orthogonal Harmonic Signals of the Generalized Class

open access: yesJournal of Telecommunications and Information Technology, 2021
Telecommunications transmission technologies with OFDM rely on orthogonal harmonic signal (OHS) systems. The criteria applicable to synthesizing OHS systems of the generalized class, including both classical signals and signals whose duration exceeds ...

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.

Zero Padding or Cyclic Prefix: Evaluation for Non-Orthogonal Signals

open access: yesIEEE Communications Letters, 2020
The debate of using zero padding (ZP) instead of a cyclic prefix (CP) for enhancing channel estimation and equalization performance is a recurring topic. This is particularly true for orthogonal signals, such as orthogonal frequency division multiplexing
