On the Rate-Exponent Region of Integrated Sensing and Communications With Variable-Length Coding
Ioannis Papoutsidakis, George C. Alexandropoulos
This paper considers the achievable rate-exponent region of integrated sensing and communication systems in the presence of variable-length coding with feedback. This scheme is fun…
An Achievability Bound for Variable-Length Stop-Feedback Coding over the Gaussian Channel
Ioannis Papoutsidakis, Robert J. Piechocki, Angela Doufexi
Feedback holds a pivotal role in practical communication schemes, even though it does not enhance channel capacity. Its main attribute includes adaptability in transmission that al…
Efficient Evaluation of the Probability of Error of Random Coding Ensembles
Ioannis Papoutsidakis, Angela Doufexi, Robert J. Piechocki
This paper presents an achievability bound that evaluates the exact probability of error of an ensemble of random codes that are decoded by a minimum distance decoder. Compared to…
Non-Asymptotic Converse Bounds Via Auxiliary Channels
Ioannis Papoutsidakis, Robert J. Piechocki, Angela Doufexi
This paper presents a new derivation method of converse bounds on the non-asymptotic achievable rate of discrete weakly symmetric memoryless channels. It is based on the finite blo…
