| Oct 27, 2015 at 7:41 | comment | added | Neil_UK | @Tom Carpenter Do we mean the same thing by BER? Are you doing some devil's advocate thang by saying a BER=1 is just a logical inversion of every bit, and therefore the original message can be decoded? Real systems tend to operate with a BER in the range 0 to 0.2, for a recoverable level of errors. Anything above 0.2 is unusable. If BER = Bit Error Rate, then 100% noise should be BER=0.5. If BER = Block Error Rate, then 100% noise would be BER=1.0 | |
