Rate Allocation and Adaptation for Incremental Redundancy Truncated HARQ [PDF]
IEEE Transactions on Communications, 2013 This paper considers incremental redundancy hybrid ARQ (HARQ) transmission over independent block-fading channels. The transmitter, having no knowledge of the instantaneous channel state information (CSI) can or - allocate the transmission rate knowing the statistics of the channel, or - adapt the transmissions rates using the outdated CSI, i.e., the ...

On Power Allocation for Incremental Redundancy Hybrid ARQ
IEEE Transactions on Wireless Communications, 2015We study the power allocation for incremental redundancy (IR) hybrid automatic repeat request (HARQ) in block fading channel where causal channel state information is known at both the transmitter and the receiver. In IR-HARQ, the traffic is assigned into consecutive transmission rounds, and at each round, the instantaneous mutual information that is ...

Performance of EGPRS incremental redundancy in interference-limited environments [PDF]
The 5th International Symposium on Wireless Personal Multimedia Communications, 2003 Incremental redundancy (IR), an established hybrid-ARQ technique, has been proposed as an adaptive link level mechanism in third-generation and evolved second-generation wireless systems such as the Enhanced General Packet Radio Service (EGPRS). In this paper, three alternative EGPRS incremental redundancy ARQ algorithms of low (IR-ARQ1), medium (IR ...

Soft Incremental Redundancy for Distributed Turbo Product Codes [PDF]
2010 7th IEEE Consumer Communications and Networking Conference, 2010 In this paper, we propose a Distributed Turbo Product Code (DTPC) with soft information relaying over cooperative network using block Extended Bose Chaudhuri Hochquenghem (EBCH) codes as component codes. The source broadcasts extended EBCH coded frames to the destination and to a preassigned relay.

Reliability-Based Incremental Redundancy With Convolutional Codes
IEEE Transactions on Communications, 2005Incremental redundancy, or Hybrid type-II ARQ (HARQ), algorithms use a combination of forward error correction and retransmissions to guarantee reliable packet data communications. In this work, we propose a HARQ algorithm that exploits received packet reliability to improve system performance.

Sequential decoding with an efficient incremental redundancy ARQ scheme
IEEE Transactions on Communications, 1992Sequential decoding is analyzed in conjunction with an efficient incremental redundancy automatic repeat request (ARQ) scheme using punctured convolutional coding. With the incremental redundancy ARQ scheme, whenever the decoding time of a given data packet exceeds some predetermined value T/sub max/, decoding of that data packet is stopped and ...

Adaptive Incremental Redundancy for HARQ Transmission with Outdated CSI [PDF]
2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011 We analyze the throughout achievable in transmission over block-fading channels when the instantaneous channel state information (CSI) is not available at the transmitter. Assuming operation with incremental redundancy hybrid ARQ (HARQ), we propose to adapt the transmissions rates using the outdated CSI, i.e., the one experienced by the receiver in the

Systematic Luby Transform codes as incremental redundancy scheme
IEEE Africon '11, 2011Systematic Luby Transform (fountain) codes are investigated as a possible incremental redundancy scheme for EDGE. The convolutional incremental redundancy scheme currently used by EDGE is replaced by the fountain approach. The results of the simulations performed for each incremental redundancy scheme show that the fountain approach outperforms the ...
