Sorry for the sidebar but I have a question for fharris (or anyone with experience in this area). I have been analyzing a burst FSK signal that uses a preamble consisting...

I think it stems from the autocorrelation property of ZC sequences.WikipediaThe auto correlation of a Zadoff–Chu sequence with a cyclically shifted version of...

To be sure, there are a lot of equations and confusing indexing in the Chougrani reference BUT it really does describe an effective way to skirt the CFO problem....

Check this reference which proposes a differential method to deal with (read, avoid dealing with) CFO followed by combining of like symbol-group transitions.Chougrani...

fharris: Thank you very much for your Hilbert demo code. It really helped reinforce my understanding of the 2-path half-band formulations in your text. In terms...

fharris: Don't know about the OP but I would certainly be interested in reviewing your MATLAB examples of +/-45 degree Hilbert filters.

I think the author is using the equivalency of the expressions in the last line of your excerpt to make a point about the sampling operation. The point being, once...
Perhaps obvious to others but what I found interesting in the animation was the following.As expected, the magnitude response is invariant to a nonlinear phase (vs....
Very interesting how your animation clearly demonstrates that phase can impact the interpolated points while preserving the magnitude of the original response.

To further support rrlagic's claims of design intent, the LTE Toolbox from Mathworks, which claims compliance with the Standard, provides a function lteOFDMDemodulate()...
Not sure why you want to avoid using a prng, nevertheless there are several options which may meet your requirements. As others have mentioned Box-Muller can transform...

This is one of the most interesting threads I've seen here in some time. If I wasn't so overextended I'd consider getting involved. In any event I just wanted to...
