This definition is normalized so that <math>\gamma_c(A) = 1</math> for 2-PAM.

For the special case of a binary [[linear block code]] <math>C</math> with parameters <math>[n,k,d]</math>, the nominal [[spectral efficiency]] is <math>\rho = 2k/n </math> (b/2D or b/s/Hz) and the nominal coding gain is ''kd''/''n''.

and the nominal coding gain is ''kd''/''n''.
