Variable-length coding with noiseless feedback and finite messages
2010 Conference Record of the Forty Fourth Asilomar Conference on Signals, Systems and Computers, 2010This paper considers the problem of zero-rate (fixed number of messages) variable-length coding over a memoryless noisy channel with noiseless feedback. This problem is considered from a control theoretic point of view and is modeled as a special case of active sequential hypothesis testing.

Coding for channels with low rate noiseless feedback
Proceedings of IEEE International Symposium on Information Theory, 2002Consider a binary symmetric channel where for each frame of f forward transmissions one is allowed a group of y/spl Lt/f noiseless feedback transmissions. Using set partitioning, a forward code affects the rather simple intra-set decoding, while inter-set decoding is accomplished by using a feedback strategy. A simple example with (f,g)=(2,1), a memory

Optimal state estimation over gaussian channels with noiseless feedback
IEEE Conference on Decision and Control and European Control Conference, 2011This paper addresses an optimal state estimation problem in the presence of limited communication and noiseless feedback. In this setup, the state dynamics is estimated via an additive white Gaussian channel with input power constraint. We present a new communication and estimation strategy based on Kalman-Bucy filtering theory and water filling ...

Optimal partial feedback design for MIMO block fading channels with causal noiseless feedback
IEEE International Conference on Communications, 2003. ICC '03., 2004In this paper, we focus on investigating the optimal MIMO transmission strategy for forward channel capacity and forward error exponent of the MIMO block fading channels when the feedback link is causal and has a capacity constraint. In this paper, we assume a forward MIMO block fading channel where the channel state information is estimated at the ...

Identification via noiseless channels with noisy feedback
Proceedings of the 1999 IEEE Information Theory and Communications Workshop (Cat. No. 99EX253), 2003We give an upper bound on the rate of deterministic identification code for discrete noise and memoryless channels with noisy feedback. This upper bound coincides with the lower bound of Ahlswede and Zhang (see SFB 343 Diskrete Strukturen in der Mathematik, Bielefeld, Preprint 94-010, 1994), so this gives the capacity for this type of channel.

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).

Optimum error detection codes for noiseless decision feedback
IEEE Transactions on Information Theory, 1962Summary: Iterative error-detection codes are applied to a decision-feedback communication system employing a noisy binary-symmetric forward channel and a noise-free feedback channel. The optimum (maximum information rate) code is shown to be one in which only a single parity check is made at each stage of the iteration.

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.

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.

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.
