I am working with USRPs to transmit and receive data using Simulink. At the receiving end, I want to obtain the SNR in real-time. Is it possible to achieve it in Simulink?

Here is a steps to find the SNR
  1. Obtain the noise power, by measuring the input power when there is no transmitted signal. Make sure no other signal is received either.
  2. Then measure the input power when transmitting the signal, which gives the signal + noise power. Obtain signal power by subracting the noise power, from the combined value.
Calculate the power using this block
