[Discuss-gnuradio] Error calculation

[farid mihoub]

Hello,

I am sending some samples of type byte (unsigned char), in the receiver side I get the estimated samples,

for my application every byte represent a value between 0 and 255, so I need to calculate the MSE (mean square error),

                                  _________                        ______

Exp: 1000 bytes ------|transmitter |----channel-->|receiver|------1000 estimated bytes.

Questions:

1- how can I ensure that the received bytes will be in the same order  as the transmitted ones.

2- how can I extract that data to use it with Matlab or octave.

 

Best regards.
