Desultory CSP: More Signals from SigIDWiki.com

More real-world data files from SigIDWiki.com. The range of spectral correlation function types exhibited by man-made RF signals is vast.

Let’s look at a few more signals posted to sigidwiki.com. Just for fun.

  1. Chad Spooner on Frequency Shift (FRESH) Filtering for Single-Sensor Cochannel Signal SeparationJuly 11, 2026

    Those are not spectral densities in (37)-(38). They are spectral correlation functions. More accurately, if the superscript is zero, the…

  2. John on Frequency Shift (FRESH) Filtering for Single-Sensor Cochannel Signal SeparationJuly 8, 2026

    Thanks! I do have another question. I understand the idea behind the math involving the matrices and convolution, but I…

  3. Chad Spooner on Frequency Shift (FRESH) Filtering for Single-Sensor Cochannel Signal SeparationJuly 6, 2026

    Welcome to the CSP Blog John! Glad you answered your own question. The function in your previous comment computes the…

  4. John on Frequency Shift (FRESH) Filtering for Single-Sensor Cochannel Signal SeparationJuly 6, 2026

    Never mind, I solved it. I just did not look hard enough at first.

  5. John on Frequency Shift (FRESH) Filtering for Single-Sensor Cochannel Signal SeparationJuly 6, 2026

    This is probably a silly question, but what PSD method did you use to generate the PSD plots? I think…

  6. Stephan on CSPB.ML.2018R2.NFJuly 4, 2026

    I haven't commented in a while so I'll leave a bit of a pulp comment: Downloading this now and running…

  7. Chad Spooner on SPTK: Sampling and The Sampling TheoremJune 10, 2026

    Here is Mansoor's figure:

  8. Chad Spooner on Cyclostationarity of Direct-Sequence Spread-Spectrum SignalsJune 9, 2026

    Welcome to the CSP Blog XY! Thanks for the comment. will DSSS signals always present such clear peak characteristics regardless…

  9. XY on Cyclostationarity of Direct-Sequence Spread-Spectrum SignalsJune 8, 2026

    Hi there, hope you get a chance to see this question. I've been following your mathematical derivations regarding DSSS signals,…

  10. Mansoor Wahab on SPTK: Sampling and The Sampling TheoremJune 7, 2026

    When sampling a RF/bandpass signal with carrier frequency, you have several options: 1) Downconvert the signal to baseband with analog…
