Hello everyone! I am trying to do my thesis and I have to do some signal processing. I have to do spectral correlation and I see a parameter α called cyclic frequency. valentines day gifts for her
Although I have found information about how to find it , I haven't found an explanation of what it is. Can someone please help me understand what it is. Thanks in advance!
"cyclic" and "frequency" are redundant. I suspect if you explain it so we can understand the problem, you will discover your answer.
In cyclostationary processing applications, α is the separation frequency and f is the location frequency to define a signal's spectral components at f + α/2 and f - α/2. If there is correlation in a signal's spectral components at these frequencies defined by α and f, the signal has second-order periodicity, or is cyclostationary, at cycle frequency α and spectrum frequency f. This theory is based on cross-spectral analysis of frequency-translated versions of a signal. With these definitions, a signal's periodic statistics can be measured and processed.
A great reference on the subject is William A. Gardner's book: Statistical Spectral Analysis, A Nonprobalistic Theory, Prentice-Hall, 1988.
Consider this copy for $104 (https://www.abebooks.com/servlet/BookDetailsPL?bi=...)
Generally Abe Books is a much better source of old text books than Amazon.
Gardner's book costs over $1000 and is unavailable through my library. Do you have a more reasonable reference on the subject?
There is actually a pdf version available online by, apparently, the author himself or at least his university ucdavis.
Thanks for this interesting subject I ignored.
Cyclostationarity in Communications and Signal Processing, edited by William A. Gardner, IEEE Press, 1994.
You may be able to find a copy of this book for much less.
