I am a new student and trying to to measure the power and voltage output from B200 SDR device (https://www.ettus.com/content/files/b200-b210_spec_sheet.pdf) using...
doing this way: https://www.dropbox.com/s/le4ppw32l4sp5ll/RX1.dat?...https://www.dropbox.com/s/zr04pff9skeh8cn/TX.dat?d...format long;%% initial values:nsamps ...
@kaz:So, I have to interpolate rate of 125 first on signal1 and signal2, then I have 2 new signals let say s1 and s2.I can cross-correlation s1 and s2 to get the...
@kaz: very helpful, I also look at the maxlag parameter of the xcorr function, do you think it can be used? And, that would be nice if you can show me in the matlab...
I just discussed with the professor, he also mentioned the expectation for the delay will be 3ns or better (less than 1m).I do not have continue function, I jsut...
so, If this code is still getting in microsecond, So I have to check to hardware?we can see the sample rate is 8MHz, the the wavelength = speed of light / sample...
they could be same sampling rate, same centre frequency, and maybe different in phase.and and also you can see in detail this topic, i posted couple days ago but...
they are same sampling rate, but not sure on center frequency and phase.and also you can see in detail this topic, i posted couple days ago but no one replied or...
here is my TX and RX data, and trying to show you the reason why I cut RX data into 2.and If I correlate the pair once, I can have this:that make me confuse, if...
I have 2 PERFECT data of the transmitter and receiver. From 2 data, I can calculate the delay estimation:Fs = 8e6; % sample rate
...
for i = 1:2
[cc_correlation,lag]...
@laurentlefaucheur:
- I am sorry I can not run this code, because of this:
datachunkLeft = audioread('RX.WAV');- My data file is RX.dat, but not RX.WAV...
@ dgshaw6 :- you can forget about this line, because I just want to set automatically recognize the time from RX data (for example: 1, 5, 10, 20 seconds data)....
@ krasin: - Yes, They are pulses.- I have Transmitted data (TX.dat) which is called TX. - I send this data to another device, then I have Received data which is...
@Tim Wescott: Thank you for your suggestion, I hope you can look at my new code and give me some comment.My new code which reply with Mr "Rick Lyons" below. You...
@Rick Lyons: Thank you for your suggestions, I did this way, I used the "transmit"signal (without noise added), then put it in the function lagmatrix, (we can...
