On Some Properties of Capacity in Gaussian Channels with Feedback
نویسندگان
چکیده
We show that the capacity Cn,FB(P ) of the Gaussian channel with feedback is a concave function of P , and give two types of inequalities: both 1 α Cn,FB(αP ) and Cn,FB(αP ) + 1 2 ln 1 α are decreasing functions of α > 0. As their application we can obtain two upper bounds on the capacity of discrete time blockwise white Gaussian channel with feedback.

Gaussian Z Channel with Intersymbol Interference
In this paper, we derive a capacity inner bound for a synchronous Gaussian Z channel with intersymbol interference (ISI) under input power constraints. This is done by converting the original channel model into an n-block memoryless circular Gaussian Z channel (n-CGZC) and successively decomposing the n-block memoryless channel into a series of independent parallel channels in the frequency dom...
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 کاملBounds for Multiple-Access Relay Channels with Feedback via Two-way Relay Channel
In this study, we introduce a new two-way relay channel and obtain an inner bound and an outer bound for the discrete and memoryless multiple access relay channels with receiver-source feedback via two-way relay channel in which end nodes exchange signals by a relay node. And we extend these results to the Gaussian case. By numerical computing, we show that our inner bound is the same with o...
متن کاملOn Continuous-Time Gaussian Channels
We establish natural connections between continuous-time Gaussian feedback/memory channels and their associated discrete-time versions in the forms of sampling and approximating theorems. It turns out that these connections, together with relevant tools from stochastic calculus, can enhance our understanding of continuous-time Gaussian channels in terms of giving alternative interpretations to ...
متن کاملRandom coding for additive Gaussian channels with feedback
Ahstrurf -A random coding strategy for discrete-time additive Gaussian noise channels with feedback is analyzed. It has long been known that feedback may increase the capacity of such channels as long as the additive noise process is not white. We prove that a strictly positive gain is always achieved. In addition, we prove that as the signal power goes to zero the ratio of feedback capacity to...
