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

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).

On the significance of periodic signals in noise analysis of GPS station coordinates time series
GPS Solutions, 2016 Each of the GPS-derived time series consists of the deterministic (functional) and stochastic part. We propose that the deterministic part includes all periodicities from 1st to 9th harmonics of residual Chandler, tropical and draconitic periods and ...
