Index Coded Automatic Repeat Request (ARQ) [PDF]
In this paper, an index-coded Automatic Repeat Request (ARQ) is studied in the perspectives of transmission efficiency and memory overhead. Motivated by reducing significant computational complexity from huge matrix inverse computation of random linear ...

Performance of Cognitive Selective-Repeat Hybrid Automatic Repeat Request
In this paper, a novel transmission protocol is proposed based on the classical selective-repeat hybrid automatic repeat to access a primary user (PU) channel, which is referred to as the CSR-HARQ.

Coordinated Hybrid Automatic Repeat Request [PDF]
We develop a coordinated hybrid automatic repeat request (HARQ) approach. With the proposed scheme, if a user message is correctly decoded in the first HARQ rounds, its spectrum is allocated to other users, to improve the network outage probability and the users' fairness.

Performance of Cognitive Stop-and-Wait Hybrid Automatic Repeat Request in the Face of Imperfect Sensing [PDF]
The cognitive radio (CR) paradigm has the potential of improving the exploitation of the electromagnetic spectrum by detecting instantaneously unoccupied spectrum slots allocated to primary users (PUs).

Automatic-repeat-request error-control schemes [PDF]
ERROR DETECTION incorporated with automatic-repeatrequest (ARQ) is widely used for error control in data communications systems. This method of error control is simple and provides high system reliability. If a properly chosen code is used for error detection, virtually error-free data transmission can be attained.

Concatenated coding and hybrid automatic repeat request for wiretap channels
In this study, the authors propose an equivocation scheme for wiretap channels, which is composed of bit‐extension mapping, coset coding and hybrid automatic repeat request (HARQ). The inner bit‐extension code and outer coset code are used for equivocation of a wiretapper channel, whereas the HARQ scheme is to mitigate noisy errors in a main legitimate
