Time Delay Estimation of Cyclostationary Signals on PCB Using Spectral Correlation Function
P. 184–187.
This paper presents an approach to estimating delays of the cyclostationary signal propagating through tracks of the data bus of a printed circuit board (PCB). The signal path is described by the series of delays estimated using cyclostationary characteristics in the frequency domain. A brief overview of cyclostationarity phenomena is given alongside with the designed practical algorithm performing wideband estimation of the spectral correlation density of the signal. Delay estimations obtained with the proposed approach based on cyclic spectral correlation function are much closer to the values evaluated geometrically on planar scheme than delays calculated by means of well-known generalized cross-correlation algorithm (GCC). The proposed algorithm is verified by the results of experiments featuring FPGA board.

The paper is aimed at investigating the difference between different forms of time-varying autocorrelation function (TVACF) used for the quantitative expression of the second-order statistical properties exhibiting by non-stationary random processes. The generalized form of TVACF is proposed where the position of the current time moment can be set by means of additional parameter. The ...

The signal detection problem for cyclostationary signals is addressed within the fraction-of-time probability framework, where statistical functions are constructed starting from a single time series, without introducing the concept of stochastic process. Single-cycle detectors and quadratic-form detectors based on measurements of the Fourier coefficients of the almost-periodically time-variant cumulative distribution and probability density functions are ...

This paper proposes a cyclostationary based approach to power analysis carried out for electric circuits under arbitrary periodic excitation. Instantaneous power is considered to be a particular case of the two-dimensional cross correlation function (CCF) of the voltage across, and current through, an element in the electric circuit. The cyclostationary notation is used for deriving ...

This chapter presents the algorithm for estimating spectral correlation
function of a random process that is a valid bi-frequency description of the probabilistic
properties of any wide-sense cyclostationary process and relates to its cyclic
autocorrelation function via Fourier transform. The key point of the algorithm is that
it is based on the two-dimensional discrete Fourier transform of the sample ...

The paper deals with cyclostationarity as a natural extension of stationarity as the key property in designing the widely-used models of random processes. The comparative example of two processes, one is wide-sense stationary and the other is wide-sense cyclostationary, is given in the paper and reveals the lack of the conventional stationary description based on ...
