Hi
I have a project about simulation channel in communication using matlab and I calculate the BER, it was BER=1, I would ask if this value good or bad in the channel.
thanks
what a strange result
This result mean when you send 1 u receive it 0 and when u send 0 u receive it 1
I think u must check ur code and the way u model the channel and the way u calculate BER
Remember BER = number of error bits / total number of bits
max ber is 0.5. It means that 0's are changed to 1's and 1's are changed to 0's. I dont think if ber can be 1. As if ber =1 just apply NOT gate and BER will become 0.

well if the BER=1, then Bits Recieved is NOT of Bits Transmitted. so BER=1 means just put nOT (i.e, make 1 to 0 and 0 to 1 ) and BER will become 0. That why the max BER is 0.5, which means that half of the 1's became 0's and half of the 0's become 1's and even if we use NOT gate it will remain same i.e. BER will be 0.5. So max BER is 0.5 and MIN BER is 0.
