Thank you for the replies Eric!

1.You said about using file_sink , but in my case I do not think that will work because I need to make real time precessing of the signal. If I use files it will take to long.
2. My theses is about simulating the acquisition of 2 signals (co-polar and cross-polar ) from a satellite (10.7 Mhz) and estimate their amplitudes and relative phase. So the first thing I am trying to do is to estimate the co-polar having an SNR of 14 db and the power about 10dbm. To do that I have set the NCO 10.7Mhz, and decim_rate to 256 in order to bring the signal to its base-band and I was thinking of creating a loop of let's say 10 times in which we acquire  256 or 512 samples using a window, perform the fft and from here to extract the maximum power bin and it's frquency, perform an avarage on this powers and the display the result in a window.

I got stucked on this for almost 2 weeks.:(

Thank you
