Samples IQ

[Antonio Ramos Morales]

hola , yo tengo un problema parecido y queria saber si pueden hecharme una mano ,,, tengo estas muestras de IQ:q": [195,73,-88,187,-170,-95,131,-184,188,137,-105,206,-140,-132,146,-188,-208,95,198,-95,-234,130,198,-112,-268,-23,244,21,-242,-33,224,10,-217,-92,226,54,-248,-28,163,84,-202,-140,178,205,-177,-95,94,117,-154,-131,36,244,-111,-209,53,316,-46,-206,-57,203,-2,-196,-67,268,119,-246,-62,179,165,-219,-84,168,120,-99,-145,171,232,-100,-187,70, 198,-77,-233,48],

donde  CTElength ThelengthoftheCTE Unit:8us;2~20:turnonCTEsampling,0~1:turnoff. Unit:8us;2~20:turnonCTEsampling,0~1:turnoff.
Sampling spacing = 2
Switchspacing = 2
Sample offset(in number of 16M cycles) = 1

Switch offset(in number of 16M cycles) = 0

Switch pattern = 2,2,0,5,6,1,4,12,9,14,13,8,10

podria alguien explicarme a que antena pertenece cada IQ?

Hi

In the future, please write tickets and replies in English, as translating using Google Translate doesn't always result in something that makes sense on our end, so some guesswork is made to understand your question and answer you here. Let me know if I got something wrong:

You want to know which IQ samples correlate to which antennas on your array, correct? First off, what antenna array are you using, this one from Insight SiP or some other array?

The first antenna in your switch pattern will be the reference antenna. Then after the reference period, all the other antennas will be used in order from left to right starting with the one after the referene antenna (2 in your case). Is there a reason you've set antenna 2 both as the reference antenna and as the next one in line? And is it correct that your antenna array consists of 13 antennas, or do you have less/more than that?

Best regards,

Simon

Yes I am using it

esta de Insight SiP ,

 try changing the antenna in a circle ,12 ant

 I don't know if you would have any part of the code to get the angle and the xy position of the tag from this data, if I could abuse your wisdom to be able to make the code, I am using python....thanks
