The concept of generalized 4PAM (G4PAM) is introduced in this paper, where each 4PAM symbol includes one high bit and one low bit with non-uniformly spaced constellation. The channel capacity of G4PAM constrained additive white Gaussian noise (AWGN) channel is obtained via numeric calculation, so as these of the high and low bits in terms of independent… CONTINUE READING
