You can try the following options:
Option 1: You can use the MER Measurement Block (refer following link for documentation) to measure the signal-to-noise ratio (SNR).
Option 2: You can use MATLAB Function Block and call 'snr' function from MATLAB, 'snr' function (refer following link for documentation) returns the signal-to-noise ratio as well as total noise power.
Then, SNR(dB) = Signal Power(dB) - NoisePower(dB)
