Hi guys.
I have hard time understanding data transmitting system based hardware especially usrp. any answers or concerns must be surely appreciated.
now i am planning to confirm channel reciprocity between 2 usrps, and also using basic examples to synchronize or to estimate the channels. but i faced several problems that I got different channel phase offsets in every symbol while I got equal magnitudes from the channel. ( I also checked it by using wire that it is not depends on channel fading)
So, is there any reasons or solutions to solve this problem?
