Frequency-Domain Turbo Equalisation in Coded SC-FDMA Systems: EXIT Chart Analysis and Performance [PDF]
, 2012 In this paper, we investigate the achievable performance of channel coded single-carrier frequency division multiple-access (SC-FDMA) systems employing various detection schemes, when communicating over frequency-selective fading channels.

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.

Towards phase-stabilized Fourier domain mode-locked frequency combs
Communications Physics, 2022 Fourier domain mode-locked lasers provide coherent, wavelength swept light useful for imaging applications, but the phase relation between frequencies is not understood.

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.

Frequency Domain Repercussions of Instantaneous Granger Causality
Entropy, 2021 Using directed transfer function (DTF) and partial directed coherence (PDC) in the information version, this paper extends the theoretical framework to incorporate the instantaneous Granger causality (iGC) frequency domain description into a single ...

Adaptive frequency-domain equalization for single-carrier MIMO systems [PDF]
, 2004 Channel estimation and tracking pose real problems in wideband single-carrier wireless communication systems employing multiple transmit and receive antennas. An alternative to estimating the channel is to adaptively equalize the received symbols.

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.

Side-channel analysis in frequency domain with clustering
Dianzi Jishu Yingyong, 2021 The alignment of power traces is one of the key factors affecting the success of side-channel analysis. Frequency-domain side-channel analysis can effectively solve the alignment of power traces in the time domain.
