چکیده
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 Pinsker and Ebert) andC<C,,<C t$.

Necessary 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 کاملUpper bounds on the capacity of discrete-time blockwise white Gaussian channels with feedback
Although it is well known that feedback does not increase capacity of an additive white Gaussian channel, Yanagi gave the necessary and sufficient condition under which the capacity Cn,FB(P ) of discrete time non-white Gaussian channel is increased by feedback. In this paper we show that the capacity Cn,FB(P ) of the Gaussian channel with feedback is a concave function of P , and give two type ...
متن کاملOUTER BOUND OF CAPACITY REGION IN M-USER NON-WHITE GAUSSIAN MULTIPLE ACCESS CHANNEL WITH FEEDBACK Dedicated to Professor Hisaharu Umegaki on his seventieth birthday
The capacity region of m-user non-white Gaussian multiple access channel without feedback was exactly obtained. But it is not yet obtained in the feedback case without the upper bound of total capacity. We give the outer bound of capacity region in muser non-white Gaussian multiple access channel with noiseless and nodelayed feedback in general. Finally we remark that there are three types of o...
متن کاملOn the Feedback Capacity of Stationary Gaussian Channels
The capacity of stationary additive Gaussian noise channels with feedback is characterized as solution to a variational problem. Toward this end, it is proved that the optimal feedback coding scheme is stationary. When specialized to the first-order autoregressive moving-average noise spectrum, this variational characterization yields a closed-form expression for the feedback capacity. In parti...
متن کاملOn the Capacity of the Vector MAC and BC with Feedback
We determine the feedback capacity region of a two user Gaussian multiple access channel (MAC) with multiple antennas at the base station and a single antenna at each user. The vector MAC and broadcast channels (BC) with a single antenna at the base station and multiple antennas at each user are shown to be equivalent to scalar MACs and BCs, respectively. We also determine the capacity enhancem...
