I've found on multiple sites that convolution and cross-correlation are similar (including the tag w…
I am trying to get the fundamental frequency of a signal that only has a single pitch. I coded out t…
Suppose a random signal $x(t)=\sum\limits_{n=-\infty}^\infty Z_n \delta(t-n\tau)$, where $ z_n = Z$ …
I'm doing autocorrelation (via fft) on pure, synthetic generated sinusoids and getting unexpected ji…
I would like to know how an autocorrelation for a long binary sequence be performed? Are there many …
Are there any general assumptions for the calculation of the Hurst exponent? Does the signal need…

I know that zero shifting in the autocorrelation function is equal to its energy, yet, I would like …
How do I estimate if in recorded sound samples is present an echo caused from walls reflection ? (m…
As part of my work I am putting together a simple bursty BPSK communication system. I want to make …
A simple question as the title indicates: Let us assume that we have two signals, measured from two…
I need to compute FFT components and autocorrelation of a discrete signal. When I do not use any win…
I realize the two are derived using different algorithms, and the units are different, but from a co…
Anyone have an idea of how I can implement autocorrelation of power spectrum of one image? I tried u…
I'm reading up on Autocorrelation, but I'm not sure I understand exactly how it works and what outpu…
Context: (Disclaimer: This is NOT a comm problem). I am trying to estimate the fundamental frequen…
This is a side-trip from my snoring app. I had a crack at producing an autocorrelation of the audio…
I am currently learning about least-squares (and other) estimations for regression, and from what I …
How intuitively to understand why eigenvectors of the autocorrelation matrix are used, but eigenvect…
I have a stochastic process completely uncorrelated. Why the autocorrelation function has a delta of…
I'm trying to calculate an autocorrelation on a platform where the only accelerated primitive I have…
I have an auto-correlation function that was generated from a signal, and I am trying to extract its…
I'm trying to figure out how exactly an auto correlation corresponds to a time domain signal. Now I…
Foreword: I'll give some background here because I'm not sure all my premises are correct. I encoura…
Is a stochastic process completely described by its autocorrelation function? If not, which additio…
