Hi @kaz, I believe the channel is UE sending to eNB and eNB is estimating the UL channel response based on pilot tones from UE.I am aware LTE uses 1200 subcarriers...
Hi @kaz, I will rephrase my task below.The measurement data is indeed from a 20 MHz LTE system with 1200 subcarriers. The measurements are the estimated channel...
Hi @MarkSitkowski , thanks for taking a look at my data. Your results indeed show me that my data should produce correct results. Do you have any information on...
Hi, it is real - imaginary data on linear scale. The dimension 10 is indeed for 10 different channel measurements in 1 file.regards, cel
Hi CharlieRader, thanks for the advice! By coincidence I switched to a plot with individual dots today, exactly because the phase response is hard to read otherwise.Can...
Hi MarkSitkowski, thanks for your interest. I have prepared some npy and csv files for you at the following WeTranfer link.Included are raw complex channel measurements...
Apologies for any confusion caused, I am indeed working in telecom on a typical 4G LTE system (it is a massive MIMO research testbed but I'm not yet working on MIMO...
Hi David, thanks for the great answer!I have implemented the interpolation before doing the IFFT again (I had already done something similar before but it didn't...
You're right indeed, I have updated my comment with a result using the complex oscillation. I had to update the formula to t/N to get a visible change in the phase...
Hi, thanks for your answer josefsepp. I will try out this approach and report back. It actually sounds quite logical the factor t in the phase correction.Update:...
Hi, thanks for your answer!If I understand it correctly, I should only take first N/2 (with N=100 the ifft size) samples of my complex IFFT as the time domain impulse...
