We study a problem motivated by cognitive radio in which the primary is a packet system that employs ARQ feedback. A secondary system is allowed to transmit ...

The model leads to strategies in which the cognitive radio adaptively adjusts its input based on the primary's ARQs thereby guaranteeing the primary exceeds a ...

Absent this knowledge, we propose a scheme in which the secondary eavesdrops on the primary's ARQ and uses this knowledge to stay within its interference budget ...

In Hybrid ARQ, the original data is encoded with an FEC code, and the parity bits are either immediately sent along with the message or only transmitted upon ...

PDF | We study a problem motivated by cognitive radio in which the primary is a packet system that employs ARQ feedback. A secondary system is allowed.

This paper evaluates the throughput performances of Stop-and-wait ARQ and Go-back-N ARQ schemes on an unslotted channel or a slotted channel. In these channels, ...

Automatic Repeat Request (ARQ) is a communication technique that relies on feedback from the decoder to determine if a message has been correctly received.

Aug 1, 2009 · Abstract: This paper develops a novel framework for sharing secret keys using the well-known Automatic Repeat reQuest (ARQ) protocol.

nf , no are the size of the total frame in bits and the overhead bits simultaneously. The transmission efficiency of Stop-and-wait ARQ is given by the ratio ...
