Gaussian 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 کاملCoding Schemes and Asymptotic Capacity of the Gaussian Broadcast and Interference Channels with Feedback
A coding scheme is proposed for the memoryless Gaussian broadcast channel with correlated noises and feedback. For all noise correlations other than ±1, the gap between the sumrate the scheme achieves and the full-cooperation bound vanishes as the signal-to-noise ratio tends to infinity. When the correlation coefficient is −1, the gains afforded by feedback are unbounded and the prelog is doubl...
متن کاملFeedback Capacity of Gaussian Channels Revisited
In this paper, we revisit the problem of finding the average capacity of the Gaussian feedback channel. First, we consider the problem of finding the average capacity of the analog colored Gaussian noise channel where the noise has an arbitrary spectral density. We introduce a new approach to the problem where we solve the problem over a finite number of transmissions and then consider the limi...
متن کاملNecessary and Sufficient Condition for Gaussian Feedback Capacity to Increase
The problem considered in this paper is whether the capacity of a discrete time Gaussian channel is increased by feedback or not. It is well known that the capacity of a white Gaussian channel under the average power constraint is not changed by feedback. In the previous paper [7] we gave some sufficient conditions under which the capacity of a non-white Gaussian channel is increased by feedbac...
متن کاملOn Some Properties of Capacity in Gaussian Channels with Feedback
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.
