    Relay-based resource allocation in cognitive networks by Shi-bing ZHANG, Hao-ye ZHANG, Xue LI, Zhi-hua BAO

    Published 2011-11-01
    “…Based on the optimal pairing the subcarriers of uplink and downlink,a spectrum resource allocation algorithm was proposed according to the subcarrier characteristics of the uplink and downlink in cognitive relay networks.The algorithm allocated the subcarriers in downlink according to the difference of subchannel gains.It assigned the subcarriere in uplink to minimize the power of every source nodes and relay nodes,and distributed the bits and powers of all subcarriers to satisfy the immediate request.It could decrease the power transmitted and increase the throughput of the system.The simulation results show that the algorithm proposed reduces the per bit power by 1.5~3 dBμW and improve the performance by one order of magnitude in bit error rate compared with the heuristic centralized scheme and distributed feedback-assisted-transmit power allocation algorithm.…”

    Multi-component network product coding for cooperative relaying by Ming GAN, Hui LI, Xu-chu DAI

    Published 2013-06-01
    “…Network product coding, a promising and anti-fading technology, can not only outperform the conventional XOR based network coding scheme in bit error rate performance, but also reduce the number of relays required in the network. A multi-component network product coding scheme was designed for cooperative multiple access scenarios. …”
