# We now use Lemma 1 to prove the main result of this subsection.Proposition 1: A capacity-achieving input distribution for the average power constrained AWGN-QO channel (1) must have bounded support. Proof: Assume that the input distribution F * achieves 1 the capacity in (4) (i.e., I(F * ) = C), with γ * ≥ 0 being a corresponding optimal Lagrange parameter in the KKT condition.
