hi all,
sometimes i found error rate it will result 3.4 or 2.3 or 4.0 something
like this but in reality BER
cant be greater than 1 so what is meaning of BER result picture has
been added of how i find BER.

One of GRC’s first blocks.
So that block is expecting an input stream of bytes and on the other
port, the same input stream but randomly “messed up”. But if you are off
by even one byte, its going to fail correlating anything and give you
50% error rate or something.
It might also be expecting a symbol per byte, and I think the byte
stream in that flow graph, the bits are packed back to back – which
might explain the strange numbers.
I hope that helps,
