Frequency Domain Analysis of Load Frequency Control Using PIDTune Model Standard
Andalas Journal of Electrical and Electronic Engineering Technology, 2023 The load frequency control system aims to regulate the frequency in the electric power system at a normal value with a predetermined tolerance limit. In practice, the load frequency control system does not always operate optimally, therefore a controller

Robust Audio Watermarks in Frequency Domain
Journal of Telecommunications and Information Technology, 2014 In this paper an audio watermarking technique is presented, using log-spectrum, dirty paper codes and LDPC for watermark embedding. This technique may be used as a digital communication channel, transmitting data at about 40 b/s.

WDIG: a wavelet domain image generation framework based on frequency domain optimization
EURASIP Journal on Advances in Signal Processing, 2023 In the end-to-end image generation task, the spatial domain of pixel space cannot explicitly separate the low-frequency general information such as texture and color from the high-frequency detail information such as structure and identity.

Cointegration in frequency domain [PDF]
Journal of Time Series Analysis, 2002 Existence of a cointegration relationship between two time series in the time domain imposes restrictions on the series zero‐frequency behaviour in terms of their squared coherence, phase and gain, in the frequency domain. I derive these restrictions by studying cross‐spectral properties of a cointegrated bivariate system.
