On the reliability function of the ideal Poisson channel with noiseless feedback

IEEE Transactions on Information Theory, 1993
A coding scheme for the channel under peak power and average power constraints on the input is presented, and its asymptotic error exponent is shown to coincide, at all rates below capacity, with the sphere packing error exponent, which, for the case at hand, is known to be unachievable without feedback for rates below the critical rate. An upper bound

Coding for channels with low rate noiseless feedback

Proceedings of IEEE International Symposium on Information Theory, 2002
Consider 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

Optimum error detection codes for noiseless decision feedback

IEEE Transactions on Information Theory, 1962
Summary: 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.

Optimal state estimation over gaussian channels with noiseless feedback

IEEE Conference on Decision and Control and European Control Conference, 2011
This 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 ...

A Signalling Scheme for Frequency-Shift-Keying Channels With Noiseless Feedback

IEEE Transactions on Communications, 1972
Stochastic approximation is applied to the design of a frequency-shift-keying (FSK) feedback scheme. FSK signals are transmitted over a channel with additive white Gaussian noise (AWGN) and the frequency estimate is fed back to the transmitter. A signaling scheme similar to the Schalkwijk-Kailath amplitude-shift-keying (ASK) scheme is derived and ...

Optimal partial feedback design for MIMO block fading channels with causal noiseless feedback

IEEE International Conference on Communications, 2003. ICC '03., 2004
In 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), 2003
We 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.

Variable-length coding with noiseless feedback and finite messages

2010 Conference Record of the Forty Fourth Asilomar Conference on Signals, Systems and Computers, 2010
This 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.

A sequential transmission scheme for the multiple access channel with noiseless feedback

2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009
In this paper we study transmission of information over a multiple access channel (MAC) with noiseless feedback. We formulate this problem as a decentralized stochastic control problem, the three controllers being the decoder and the two encoders who, in the presence of limited information about each other, decide what to transmit at each time instance,
