hi

I want to ask a small question , what is the input BER in case of deep space comm. ?

Note that I am not asking about the output required BER ( 10^-5 or 10^-6) , I want to know the real range of input BER in practical life.

waiting for any answers or hints.

regards
 

I do not know the exact value, but in the past they used 3/4 of the bits for error control. They then probably used the data to find individual points which were fliers and they were corrected by averaging the surrounding points.
