A Novel Hybrid ARQ Scheme Based on Shift Column Permutation Bit Interleaving for OFDM Systems
—In this paper, a novel hybrid ARQ scheme based on shift column permutation bit interleaving is proposed for OFDM systems. When a packet is requested for retransmission, we can u...

Mitigating the Effects of RF Interference through RSSI-Based Error Recovery
On a common sensor node platform (Telos) we sample RSSI with high frequency during packet reception. We find that a packet collision (RF interference) often manifests as a measurab...

Bits through ARQs
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 in the same frequency b...

ARQ by Subcarrier Assignment for OFDM-Based Systems
We consider two automatic repeat request (ARQ) schemes based on subcarrier assignment in orthogonal frequency-division multiplexing (OFDM)-based systems: single ARQ subcarrier assi...

On the Throughput of Secure Hybrid-ARQ Protocols for Gaussian Block-Fading Channels
—The focus of this paper is an information-theoretic study of retransmission protocols for reliable packet communication under a secrecy constraint. The hybrid automatic retransm...
