Position-Based Relaying with Hybrid-ARQ for Efficient Ad Hoc Networking
This paper presents and analyzes an integrated, cross-layer protocol for wireless ad hoc networking that utilizes position location (e.g., through an onboard GPS receiver) and jointly performs the operations of network-layer relaying and link-layer ARQ ...

Channel Constrained Multiple Selective Retransmissions for OFDM System: BER and Throughput Analysis
Hybrid automatic repeat request (HARQ) retransmission is an effective method to combat time-variant channel fading. Conventional HARQ methods initiate retransmission of failed packet without exploiting channel knowledge.

Corrections to “Efficient Design of Multi-Packet Hybrid ARQ Transmission Scheme Based on Polar Code”
In the above article [1], we did not pay enough attention to distinguishing the contributions between our work and article [2] clearly. Potential deficiencies in article writing may cause controversy or confusion to readers. We would like to provide some

Throughput-efficient Relay assisted Hybrid ARQ [PDF]
Reliable data transmission within wireless communication systems can be obtained via various means, including (i) Hybrid Automatic Repeat reQuest (HARQ) mechanisms which allow retransmission of incorrectly decoded packets; (ii) Additional nodes, called relays, which may also help the transmission by retransmitting these packets.

Throughput of nonbinary type-II hybrid ARQ with adaptive modulation [PDF]
Hybrid Automatic-Repeat-reQuest (ARQ) combines the advantages of ARQ and the Forward-Error-Control (FEC), and can achieve good throughput with very low bit error rate (BER). A nonbinary HARQ was proposed and analyzed in terms of throughput.
