Radio telecommunications; Bit Error Rate (or BER) is the percentage of
bits that are expected or calculated to be in
error. BER is affected by things like
symbol rate,
constellation size,
communications bandwidth, hardware/voltage glitches,
DSP speed, etc. Anything that adds
complexity has a negative effect on BER.
