Application of Fourier Transform-based Cross-correlation in Determining Breaking Water Wave Phase Velocity from Station-to-Station Free Surface Elevation Time Series

Water waves were produced in a laboratory wave flume that propagated and broke as plunging waves on a 1:20 beach slope. In order to distinguish changes in wave dynamics as the waves propagated from deep water to the shore, free surface elevation time series were then measured along the flume. A pair of parallel-wire capacitive…

Recent Study on Periodic Binary Signals with Zero Cross Correlation Based on Walsh Sequences

Periodic binary signals coded using Walsh orthogonal functions are considered in this research. In modern communication, telemetric and optical networks, binary coded signals are used. For periodic signals, it is shown that there are classes of signals that do not have reciprocal frequency components with a size of N = 2n (n = 1 ,…
