Non-zero DFT components where zero is expected?
Started by 3 years ago●6 replies●latest reply 3 years ago●284 viewsThis question has been asked before in dsp.stackexchange.com but I am reposting it here because very few questions are answered on that site.Edit: I got a few replies...
Compressed Sensing in DOA estimation
Started by 3 years ago●125 viewsI'm trying to apply the compressed sensing theory (CoSaMP algorithm)
to the DOA estimation in FMCW ULA (made of 48 elements). In the
dechirped signals processing...
Utility of Bit Reversal as (I)FFT Function Parameter
Started by 3 years ago●8 replies●latest reply 3 years ago●432 viewsAs a follow up to a post I made on stackexchange [here][1]. In reference to the CMSIS/DSP Float32 FFT implementation, found [here][2], starting on line ```1162```....

fractional delay filter for non real time applications ?..
Started by 3 years ago●6 replies●latest reply 3 years ago●166 viewsHello,Hi guys,I would like to create fractional delay filter that can be applied on a signal for non real time applications. My approach is to apply a linear phase...
Power mapping from analogue domain(dBm) to digital domain
Started by 3 years ago●7 replies●latest reply 3 years ago●733 viewsHi All, A standard says “-152dBm RF power should map to 1 LSB digital domain (at final stage). In our case by the digital domain I mean the following stages:...
The size of an FIR filter for PDM-PCM conversion
Started by 4 years ago●15 replies●latest reply 3 years ago●1522 viewsI have been trying to understand how the conversion from PDM to PCM happens so that I could interface with a microphone. I have been doing some research online and...
I have some image data that I want to smooth out, but I want it to smooth out nicely to the edges.Fourier transforms wouldn't do this without windowing -- if you...
Multi-filter Parks McClellan algorithm
Started by 3 years ago●13 replies●latest reply 3 years ago●307 viewsHi everyone, There are of course, many situations where the design of a single linear-phase FIR filter may be accomplished using the Parks McClellan algorithm....
Autocorrelation of OFDM Signal ?..
Started by 3 years ago●3 replies●latest reply 3 years ago●215 viewsHello,I have captured OFDM I-Q data at IF. I have down-converted to it to base-band and then simply performed autocorrleation. I was trying to find a clear peak...
