I am using a GRC flowgraph for testing the energy detection algorithm for cognitive radio.I want to update my threshold for probability detection by estimating the SNR of the channel.
However, for this, I need a feedback loop, which I want to know how to implement. Regards, Sagnik Basu B. Tech | 2013-2017 Dept. of Electronics and Communication NIT Rourkela M: 8337942928
