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...
hardware FFT coefficients .vs. np.numpy.fft.rfft
Started by 3 years ago●13 replies●latest reply 3 years ago●510 viewsWe 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...
LTE delay measurement resolution?
Started by 3 years ago●5 replies●latest reply 3 years ago●200 viewsHi All, I am trying to model a well-known delay measurement algorithm in LTE Prach. Let me put it in simpler terms. The mobile user (UE) generates a signal of length...
Communication between ARM and DSP
Started by 3 years ago●9 replies●latest reply 3 years ago●1007 viewsHi all,I am a newbie to DSP. Now our company wants to develop a product combine ARM & DSP. At the beginning, we were thinking about to use TI's am57x or keystone series...

PLL fun : some personnal work that I'd like to share
Started by 3 years ago●10 replies●latest reply 3 years ago●258 viewsA year ago, I've started working on some interactive apps to help visualize some engineering concepts that may be difficult to grasp for a beginner. I thought this...
I have an application where I am computing a purity value, because I'm interested in how much noise is present. Since I don't have a full spectrum measurement...
Is RMS a good metric to estimate gain
Started by 3 years ago●8 replies●latest reply 3 years ago●347 viewsI have two vectors V1 and V2. V1 is the source signal vector and V2 being the (possibly) degraded (attenuated/amplified) output signal. I have calculated the RMS...
