On optimal transmission strategies for channels with noiseless feedback
2016 IEEE International Symposium on Information Theory (ISIT), 2016The discrete time channel AWGN(A) with additive white Gaussian noise, strict power constraint and noiseless feedback is considered. The best error decoding exponent is investigated, limiting to the case of non-exponential number of messages (i.e. the rate of transmission R = 0).

Capacity-equivocation region of a special case of wiretap channel with noiseless feedback
Journal of Communications and Networks, 2015 The general wiretap channel with noiseless feedback is first investigated by Ahlswede and Cai, where lower and upper bounds on the secrecy capacity are provided in their work. The upper bound is met with equality only in some special cases. In this paper, we study a special case of the general wiretap channel with noiseless feedback (called non ...

The capacity of Markov channels with noiseless output and state feedback
2010 Information Theory and Applications Workshop (ITA), 2010In this paper, we derive a single-letter expression for the capacity of the finite-state channel (FSC) with delayed output and state feedback by formulating the problem in a stochastic control framework. The resulting capacity expression can be evaluated using dynamic programming.

New Results on the Wire-tap Channel with Noiseless Feedback
2018 IEEE Information Theory Workshop (ITW), 2018The model of wiretap channel (WTC) is important as it constitutes the essence of physical layer security (PLS). Wiretap channel with noiseless feedback $(WTC-NFx)$ is especially interesting as it shows what can be done when a private feedback is available.

On the zero-error capacity of channels with rate limited noiseless feedback
2018 56th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2018While it is known that feedback does not increase the small-error capacity of a discrete memoryless channel, noiseless feedback can increase the zero-error capacity from zero (without feedback) all the way to the small-error capacity. This result depends on the availability of noiseless output feedback, which gives the transmitter access to the exact ...

Sequential transmission using noiseless feedback
IEEE Transactions on Information Theory, 1963The presence of a feedback channel makes possible a variety of sequential transmission procedures, each of which can be classified as either a block-transmission or a continuous-transmission scheme according to the way in which information is encoded for transmission over a noisy forward channel.

Design optimization of noiseless feedback amplifier
1999 IEEE MTT-S International Topical Symposium on Technologies for Wireless Applications (Cat. No. 99TH8390), 1999One of the challenges in noiseless feedback amplifier (NFAs) design is to optimize the RF transformer that is required to provide proper feedback with minimum loss. Because of inherent parasitics associated with RF transformers and insufficient design guidelines, the design of NFAs and their transformers has been a difficult and time-consuming process ...

A New Achievable Rate Region for the Multiple-Access Channel With Noiseless Feedback [PDF]
IEEE Transactions on Information Theory, 2011 A new single-letter achievable rate region is proposed for the two-user discrete memoryless multiple-access channel(MAC) with noiseless feedback. The proposed region includes the Cover-Leung rate region , and it is shown that the inclusion is strict. The proof uses a block-Markov superposition strategy based on the observation that the messages of the ...

Capacity region of non-degraded wiretap channel with noiseless feedback
2012 IEEE International Symposium on Information Theory Proceedings, 2012The non-degraded wiretap channel with noiseless feedback is first investigated by R. Ahlswede and N. Cai, where lower and upper bounds on the secrecy capacity are provided in their work. However, the capacity-equivocation region has not been determined yet.
