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