As 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```....

In LTE Uplink timing is calculated at Base Station using cross correlation of PRACH when UE joins the network.Can I use Demodulation reference signal of two successive...

Hello,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...

Hi 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:...

I 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...

Hi 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....

Hello,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...

We have a FPGA system which takes input from an ADC and calculates a FFT. The system identifies the location of our frequencies of interest and sends the coefficients...

Hello.Does anybody working in the automotive radar sector know and can tel me if Phase Modulated Continuous Wave Radar is gaining popularity for mm-wave car radars...
