Review on Capacity of Gaussian Channel with or without Feedback
Let X be a real separable Banach space and X * be its dual space. Let B(X) be Borel σ-field of X. For finite dimensional subspace F of X * we define the cylinder set C based on F as follows C = {x ∈ X; It is easy to show that C(X, X *) is a fileld. Let C(X, X *) be the σ− field generated by C(X, X *). Then C(X, X *) = B(X). If µ is a probability measure on (X, B(X)) satisfying ∫ X ∥x∥ 2 dµ(x) <...
متن کاملProperties of Capacity in Gaussian Channels with or without Feedback
We give some inequalities of capacity in Gaussian channel with or without feedback. The nonfeedback capacity Cn,Z(P ) and the feedback capacity Cn,FB,Z(P ) are both concave functions of P . Though it is shown that Cn,Z(P ) is a convex function of Z in some sense, Cn,FB,Z(P ) is a convex like function of Z.
متن کاملGaussian feedback capacity
Abstracl-The capacity of time-varying additive Gaussian noise cbannels with feedback is characterized. Toward this end, an asymptotic equipartition theorem for nonstationary Gaussian processes is proved. Then, with the aid of certain matrix inequalities, it is proved that the feedback capacity C,, in bits per transmission and the nonfeedback capacity C satisfy C 5 CFB < 2C (a result obtained by...
متن کاملApproximated Capacity of the Two-User Gaussian Interference Channel with Noisy Channel-Output Feedback
In this research report, an achievability region and a converse region for the two-user Gaussian interference channel with noisy channel-output feedback (G-IC-NOF) are presented. The achievability region is obtained using a random coding argument and three well-known techniques: rate splitting, superposition coding and backward decoding. The converse region is obtained using some of the existin...
