Hi, all !! I am trying to make a simple example of signal cancellation using GRC. However, I did not get any good results.
Here is my setting Plan: sending two sine wave with different phases and receiving canceled signal (only noise) Center frequency: 5.89GHz (I am using the antenna supporting this center frequency) Sampling rate: 5MHz Frequency of sine wave: 1kHz USRP: B210 Tx GRC flow graph: signal source block + USRP sink (two channels) Rx GRC flow graph: USRP sink + QT GUI time sink When I send two sine signals, I used two RF chains in the same USRP. I received those signals at the other USRP. I expected to see canceled signals (i.e., only noise level power in time domain) but still, I see sine wave signal. I thought frequency offset in the receiving USRP is applied to both sine waves. Do I need to consider frequency offset first? Could anyone help me to solve this problem? Thank you. Regards, Inkyu
