Hi, fred and Julius. That's 802.11, I'm sure, the IEEE standard for wireless LAN. I will check out those CCK codes, another interest of mine for comms and radar. ...
Up to a point. At around 16 to 32 carriers, irrespective of modulation type, the statistics start approaching a Gaussian distribution, and PAPR is about constant. ...
Thanks, Dan. Yeah, it didn't make sense to me. Not that I'm a DSP expert, mind you. Mostly my background is RF and microwave comms, but good to know DSP as...
Late to the party, I know. But I'm not understanding the X axis in the center plots in transient's and djmaguire's posts on April 24, 2020. If h(n) is the impulse...
Reminds me of a Dilbert comic strip. Something likeFirst engineer: "Yeah, when I started programming, we didn't have any sissy icons and windows. All we had...
Great question and great answers! Yes, I'm about a month and a half behind in reading up on these DSP Related questions.
I assume you have a legitimate copy of Simulink. If so, this may be a question for the folks at MathWorks. It is possible that their DDC and/or DUC models are...
Interesting problem/challenge! I'm surprised to see this on DSP Related, though. I suppose one could build an electromechanical device whereby one could steer...
FWIW, I'm a hardware guy, and these days with Global Navigation Satellite Systems (GNSS, the most familiar probably being Global Positioning System, GPS) so common...
Oh, a veritable gold mine! Interestingly enough, Matt Donadio, author of the Tips and Tricks article on sharpening filters (really cool trick!) worked together...
Hi, Rick.No problem with the rant re: IEEE Signal Processing magazine, my least favorite IEEE magazine, at least now that you're not doing the DSP Tips and Tricks...
I second weetabixharry's take on LabVIEW; we have a large amount of LabVIEW code here at Raytheon, and it is a nightmare to maintain. I wasn't even aware that...
Great, all of them! High levels of musicianship, spot-on STEM lyrics, and a sense of humor! How can you go wrong? Lots of fun! Thanks for posting these!
Being a heavy guitar fan, I liked the Tragically Hip's "Blow at High Dough" a lot! Most of the rest of it I can take or leave.Wow is all I can say after hearing...
To some degree I agree with you, StephaneB, but even more it sounds like Emerson, Lake, and Palmer (RIP, Greg Lake). I'd swear that was Keith Emerson playing the...
Yes, nicely done! I do have some reservations about LabView, however. At the last two companies I have worked for, Broadcom and Raytheon, people were trying...
Ah, the dreaded "Hanning" window raises its ugly head again! Once again, there is the Hann or von Hann window, named after Julius von Hann, and the Hamming window,...
LOL re: MacArthur sub-genius grant! Too bad there's not such a thing! Probably many of us on this forum would apply. :)
Don't forget that cost is a nonlinear function of sampling frequency as well. I don't know what the exponent is, but it's definitely >1.
Hmmm... Maybe quaternions could help? https://en.wikipedia.org/wiki/Quaternions_and_spat...Not that I'm an expert or anything. About all I know is that by "encoding"...
Probably what we will end up doing is using the AD9361's FIR filters when the desired BW is a reasonable fraction of the sample rate and bypass them and use the...
Thanks, Rick. Like I replied to Tim above, I didn't have much choice in what hardware and software to use (not that I really am qualified to choose anyway). ...
Thanks, Tim. 1: I'm working with hardware with 3 levels of fixed-coefficient halfband filters, followed by up to 128 taps in a programmable coefficient FIR filter. ...
Hi. I'm using the Matlab Filter Wizard app to design receive and transmit filters for the Analog Devices AD9361 transceiver chip. A couple of questions that...
Up until late last year, I worked at Broadcom Ltd, so I ran into this issue. Most of the time separate front ends. I'm less familiar with ZigBee than BT and...
