Benefits of network coding towards enhancing communication quality, both in terms of robustness or data transmission rates, make it a significant candidate as a future networking technology. Conventionally, network coding is mostly used in wired infrastructures, where transmission errors between nodes are negligible. Capturing the provided benefits of network coding via straightforward extension from wired networks to wireless networks is not trivial. In addition to the challenges introduced through the wireless channel impairments, we can also capture the spatial diversity gain provided by the broadcast nature of the wireless channels. In this work, we design and implement a network-coded cooperation (NCC) system that operates in real time through the use of software-defined radio (SDR) nodes for the first time in the literature. We specifically target wireless networks. Our system is based on orthogonal frequency division multiple access (OFDMA) that provides a practical means to enable high transmission rates through the use of narrowband subcarriers. The developed testbed is composed of three source nodes, a relay node and two destination nodes. The transmission of the proposed NCC-OFDMA system is completed in two phases; the broadcast and the relaying phases. Multiplexing of source nodes' signals is achieved through OFDMA technique. In the broadcast phase, an OFDMA signal is transmitted to relay and destination nodes. In the relaying phase, the relay node first detects the OFDMA signal, generates network-coded symbols, and then transmits these symbols to destination nodes. At the end of these two phases, the destination nodes determine the source nodes' signals by using network decoders. The destination nodes make use of both the uncoded and network-coded symbols, which are received in broadcast and relaying phases, respectively. Destination nodes then perform network decoding. Through real-time bit error rate and error vector magnitude measurements, we show that the NCC-OFDMA system can significantly improve the communication quality and robustness, while enabling data transmission between multiple users, as known from theoretical analyses. Some features of this implemented NCC-OFDMA system have the potential to be included in 5G standards, due to the improved radio resource usage efficiency.

This paper firstly analyzes the transmission mechanism of the wireless broadband multi-media services in the MSW-ARQ(Multi-channel Stop-and-Wait ARQ) system. Considering the real-time multimedia service's four features (high requirement for delay but allows some loss rate, the constraints of the delay and jitter), in order to meet with professional standard, we model the real-time multimedia service packet transmission as an M [X] /G/1 queuing model for MSW-ARQ. The packet transition probability is derived by constructing steady state Markov Chain based on the method of selecting the reference packet. On the basis of equivalent service delay, we also solve the packet mean service delay. Then under the given condition, we analyze the influence of the channel number and channel environments on the mean delay through numerical simulating. The characteristics and superiorities of multi-channel transmission mechanism in wireless communication are checked enough by solving the M [X] /G/1 queuing model. So this paper provides useful thought and approach for optimizing system delay and throughput by checking the change of channel environments and the used number of parallel channels.

“…They consider orthogonal links, a single relay node and assume that relay-to-receiver link quality is always better than the quality of the source-to-receiver link. In [19] the above scheme is improved by including space-time diversity in their protocol. Finally, references [20] and [21] points out several examples that propose the use of NC to improve the communications reliability in harsh environments.…”

The wide availability of power distribution cables provides an interesting no-new-wires communication channel. However, its electrical characteristics make it a harsh environment for the data transmission purpose and prevent the deployment of services with high reliability requirements. This paper proposes and implements an OSI-Layer2 network codingbased cooperative scheme with the aim of improving communication reliability in indoor narrowband powerline channels. The proposed scheme uses random linear network coding with a sliding window and relaying. We use network coding to replace the retransmissions triggered by legacy subsequent repeat request (ARQ) schemes. We evaluate the performance of our approach in terms of throughput and delay. Regarding the throughput achieved in harsh environments, we show that our scheme often more than doubles the throughput of existing legacy ARQ schemes. At the same time, and even under the large variation of traffic characteristics, it is shown that the delay is likely to be upper bounded by a few seconds, a bound that cannot be guaranteed in other existing transmission techniques.
