“…Each time we choose the component packets in a way that more users can recover the error packets from the composite packet with less complexity [4] [5]. And we also notice that, the composite packet still meets the constraints of the channel code thanks to the linearity of channel code.…”

“…In figure 5, the performance of joint network and channel decoding-interference canceling scheme is compared with the scheme using XOR method [4] and also with the scheme using joint network coding and chase combining [5], and there are 10 users in this system. It is clear that the JNCD-IC scheme outperforms the other two algorithms, especially in middle and low Eb/N0.…”

“…The idea of network coding can also be applied to wireless networks, and a significant transmission gain can be acquired by using the broadcast nature of wireless communication systems [2] [3]. Recently, the advantage of network coding in broadcast application has drawn a lot of interest [4] [5]. It shows that the efficiency of transmission can be greatly improved by exploiting the point-to-multipoint structure of broadcasting systems.…”

“…Another limitation of [4] is that if one packet is erroneous, it will be discarded, which is not very efficient in a noisy environment. In [5], it proposes a joint chase combining and network coding scheme which combines the soft information of error packets in each retransmission phase.…”

This paper presents a novel joint network and channel decoding-interference canceling (JNCD-IC) algorithm for HARQ in wireless broadcasting system. In this system, the base station uses network coding for retransmission. In the retransmission phase, JNCD-IC scheme is proposed for the receivers to recover multiple error packets from the composite packet which is formed by XORing error packets from different receivers. Traditionally, receivers can only recovery one error packet from the composite packet using XOR method when it knows all the other packets in this composite packet as a prior, while the JNCD-IC scheme is trying to recovery multiple error packets from the composite packet by treating the network code and channel code as a single parity check product code. Simulation results for Rayleigh block fading channel show a significant increase in throughput compared to the current schemes.

“…The main idea was to intelligently mix the packets requested by the receivers so that each receiver could extract the desired packet from the mixed one, assuming that a packet intended for one user had been perfectly received by the others in previous transmissions. Following this research, a joint chase combining and NC in WBSs was proposed in [7], where the BS transmits the XOR-coded packets in response to the retransmission requests while the receivers enhance the SNR by using chase combining of multiple faulty packets.Although extensive research has been devoted to WBS based on the XOR coding, prior work mainly focused on increasing the information content in a single transmission, rather than error correction. Besides, most of them require feedback information.…”

We design and implement a network-coding-enabled reliability architecture for next generation wireless networks. Our network coding (NC) architecture uses a flexible thread-based design, with each encoder-decoder instance applying systematic intra-session random linear network coding as a packet erasure code at the IP layer, to ensure the fast and reliable transfer of information between wireless nodes.Using Global Environment for Network Innovations (GENI) WiMAX platforms, a series of point-to-point transmission experiments were conducted to compare the performance of the NC architecture to that of the Automatic Repeated reQuest (ARQ) and Hybrid ARQ (HARQ) mechanisms. At the application layer, Iperf and UDP-based File Transfer Protocol (UFTP) are used to measure throughput, packet loss and file transfer delay. In our selected scenarios, the proposed architecture is able to decrease packet loss from around 11-32% to nearly 0%; compared to HARQ and joint HARQ/ARQ mechanisms, the NC architecture offers up to 5.9 times gain in throughput and 5.5 times reduction in end-to-end file transfer delay. Our experiments show that network coding as a packet erasure code in the upper layers of the protocol stack has the potential to reduce the need for joint HARQ/ARQ schemes in the PHY/MAC layers, thus offering insights into cross-layer designs of efficient next generation wireless networks.
