Line 2: ==Example== If the uncoded [[BPSK]] system in [[AWGN]] environment has a [[Bit error rate]] (BER) of <math>10^{-32}</math> at the SNR level 34[[decibel\|dB]], and the corresponding coded (''e.g.'', [[BCH]]) system has the same BER at an SNR level of 12.5dB, then we say the ''coding gain'' = ~~3dB~~4dB-12.5dB = 1.5dB, due to the code used (in this case BCH). ==Power-limited regime==
