摘要：

We give some inequalities of capacity in Gaussian channel with or without feedback. The nonfeedback capacity C-n,C-z(P) and the feedback capacity C-n,C-FB,C-Z(P) are both concave functions of P. Though it is shown that C-n,C-Z(P) is a convex function of Z in some sense, C-n,C-FB,C-Z(P) is a convex-like function of Z.
