I am working on a research work on transmitting ECG signals compressed by Compressed sensing over wireless body area network . The signal is affected by noise and small scale fading. The normalized mean square error is used to estimate the quality of the reconstructed signal at the receiver. When I run the same m file in matlab several times, I obtain different values for the mean square error, although the same channel signal to noise ratio is used. I think this is reasonable, do you agree? If so, how can I obtain a signal value to represent the quality of the reconstructed signal at the receiver?
