Could yopu please mathematically explain why the mean and BER can be the same?

But there is problem in this block which the order of the bits should reverse. Some one have any Idea?


A simple Reverse 1D Array should do the job.  And since you are using LabVIEW 2013, change the autoindexing output tunnel to be Concatinating and then you do not need the Reshape Array code in there.

Do you know what the mean is?  It is the average.  That is exactly what you were doing before when you were adding all of the elements and the dividing by the number of elements.  That is the definition of a mean.

First of all , I do not know why my Email address is not hidden. : Smileyvery-happy: I should try to change it. 

second, I just thinking for real signals, the distributaion of the signal if gaussian  or ... can we always say that mean of the signal and BER are the same.

I am just mixing things.

No.  We are doing the mean of the number of differences.  If  the bytes are the same, we have a 0.  If they are different, we have a 1.  The mean of that (0,1) array is your BER.

it is not working. I just can see 1 byte data. the rest bytes is not shown even when I change the Nbre Byte.

Hi fatemeh,

 

I do not know why my Email address is not hidden.

Maybe because you have used it as your forum nickname?

For me it is working as expected. When I set "Nbre byte" to 4 I get 4 bytes in "array" and "array2"…

 

Best regards,

Hi fatemeh,

 

it is working with my LabVIEW version. That's how the FP looks after running the VI with "Nbre byte"=4:
