why data should be sampled at 16 kHz? #1

Open LiFengquan opened 4 years ago

LiFengquan commented 4 years ago

Hello!

I have a problem using the Multi-Channel BSS Locate Matlab toolbox. My data (magnetic waveform) was obtained by 4 antennas, at a sampling rate of 1 GHz (1^9 Hz), and a bandwidth of 140~300 MHz. I wonder why the data should be limited to be sampled at 16 kHz?

Thanks a lot.

Hi! Normally you can set the sampling rate you want. Note that the toolbox here is a subset of the Multi-Channel BSS Locate Matlab toolbox available here. I don't recall now, but the code used here has been adapted for the challenge. You may want to try to use the original toolbox.

Yo may want to change the window of analysis. By default it is 64ms, maybe to much for your application.

Let me know. Unfortunately, I don't have matlab now and I cannot try. I will try this next week. I am planning to release this code in python in the following weeks.

Thanks for your advices! I will try.

Python is a good alternative. By the way, Octave is largely compatible with Matlab and you may want to try it.
