The previous results validate the implementation of the demodulation and decoding chain for NOAA weather image on the myRio device. We obtain the same normalized signal both with and without the myRio. However, we can notice the same effect as added noise on the cross correlation on the myRio. This is due to the fact that we are working with data devided in packets (in order to send it over UDP).
