Complex Noise Analysis of DMT [PDF]
IEEE Transactions on Signal Processing, 2007 In this paper, we consider discrete multitone (DMT) or baseband orthogonal frequency-division multiplexing (OFDM) modulation and perform a detailed noise analysis which takes into account dependencies and power (variance) differences of real and imaginary part after the complex-valued discrete Fourier transform (DFT).

Evaluation of the effect of wheel tread condition on the dynamic response of PC sleepers
Nihon Kikai Gakkai ronbunshuPrestressed concrete sleepers (PC sleepers) are an important component of railway tracks. The dynamic response of PC sleepers to passing trains is influenced by various factors relating to the vehicles and tracks. However, few studies have quantitatively

Sensors, 2019 In this paper, we propose a novel approach to undertake the colorimetric camera characterization procedure based on a Gaussian process (GP). GPs are powerful and flexible nonparametric models for multivariate nonlinear functions. To validate the GP model,

AIP Conference Proceedings, 2005 Oscillators are key components of many kinds of systems, particularly electronic and opto‐electronic systems. Undesired perturbations, i.e. noise, that exist in practical systems adversely affect the spectral and timing properties of the signals generated by oscillators resulting in phase noise and timing jitter.
