Line 2: ==Example== If the uncoded [[BPSK]] system in [[AWGN]] environment has a [[Bit error rate]] (BER) of <math>10^{-2}</math> at the SNR level 4[[decibel\|dB]], and the corresponding coded (''e.g.'', [[BCH code\|BCH]]) system has the same BER at an SNR level of 2.5dB, then we say the ''coding gain'' = 4dB-2.5dB = 1.5dB, due to the code used (in this case BCH). ==Power-limited regime==
