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…
Wireless Vehicular Networks in Emergencies: A Single Frequency Network Approach
Andrea Tassi, Malcolm Egan, Robert J. Piechocki +1
Obtaining high quality sensor information is critical in vehicular emergencies. However, existing standards such as IEEE 802.11p/DSRC and LTE-A cannot support either the required d…
Novel Performance Analysis of Network Coded Communications in Single-Relay Networks
Evgeny Tsimbalo, Andrea Tassi, Robert J. Piechocki
In this paper, we analyze the performance of a single-relay network in which the reliability is provided by means of Random Linear Network Coding (RLNC). We consider a scenario whe…
The capacity of non-identical adaptive group testing
Tom Kealy, Oliver Johnson, Robert Piechocki
We consider the group testing problem, in the case where the items are defective independently but with non-constant probability. We introduce and analyse an algorithm to solve thi…
Blind Interference Alignment in General Heterogeneous Networks
Vaia Kalokidou, Oliver Johnson, Robert Piechocki
Heterogeneous networks have a key role in the design of future mobile communication networks, since the employment of small cells around a macrocell enhances the network's efficien…
