Statement − The autocorrelation theorem states that the autocorrelation function R(τ)R(τ) and the ESD (Energy Spectral Density) function ψ(ω)ψ(ω) of an energy signal x(t)x(t) form a Fourier transform pair, i.e.,R(τ)↔ψ(ω)R(τ)↔ψ(ω)In other words, the autocorrela...
The value of the autocorrelation function for a power signal at origin (i.e., atτ=τ=0) is equal to the average power (P) of that signal, i.e., R(0)=PR(0)=P Property 3 When the delay parameterττreduces, the autocorrelationR(τ)R(τ)of the power signal increases and it is...

signal autocorrelationssignal-to-interference-plus-noise-ratioThis paper presents a new unified analytical method for efficient computation of first and second order statistics of the signal-to-interference-plus-noise-ratio (SINR) in wireless communication systems. New exact ...
Here it is shown that an autocorrelation method coupled with the direct reflected time difference of arrival localization technique can successfully resolve location information. A derivation was made to model the autocorrelation of a direct signal and its overlapping reflections to illustrate that an ...

Autocorrelation can have a positive value, especially if the trend in a pattern is moving up. Downward trends are often reflected by a negative value. Such patterns are often analyzed in economics, but can also show up in mathematical analyses of signal pulses, electromagnetic fields, as well ...
A design method and principles of operation of an autocorrelational receiver of pseudorandom signals are presented. The proposed design is such that the receiver includes a circuit of reference oscillation generation which has selective properties with respect to the signal waveform. It is shown that...
