    A multi-hop D2D and social awareness based novel relay selection algorithm by Liang LI, Xinjie YANG

    Published 2022-08-01
    “…The social domain was introduced to multi-hop D2D (device-to-device) communication in cellular network scenarios, and a novel relay selection algorithm for multi-hop D2D communication under cellular network was proposed.Unlike existing relay selection algorithms, the proposed algorithm selects relays for each hop in reverse order, which reduces the signaling overhead caused by algorithm implement.Then, social domain information of mobile terminals was introduced to the algorithm and its influence on the algorithm’s performance was studied, which was found significant enough not to be overlooked hence providing useful guidance to designing algorithms in practical systems.Moreover, via extensive Monte Carlo simulations, it is discovered that the proposed algorithm outperforms the benchmarks in terms of data throughput and energy efficiency in absence of social relationship information.In a more practical implementation with social relationship information included, the proposed algorithm though naturally achieving less throughput, significantly outperforms the benchmarks in energy efficiency.…”

    Design and research of adaptive O-OFDM symbol decomposing with serial transmission system in visible light communication by Kejun JIA, Boran YANG, Minghua CAO, Suoping LI, Li HAO

    Published 2020-09-01
    “…Iterative signal clipping (ISC) and symbol decomposing with serial transmission (SDST) techniques decompose optical orthogonal frequency division multiplexing (O-OFDM) symbol into the fixed number of multiple small-amplitude symbols.However,at low O-OFDM symbol variances,the decomposition symbols contain a large amount of all-zero symbols without load information,which results in bit error rate degradation,optical power penalty and information rate reduction.Aim at this problem,an adaptive O-OFDM symbol decomposing with serial transmission (ASDST) system was proposed,the symbol decomposition was adaptively determined according to the O-OFDM symbol amplitude.Symbol decomposition was terminated until O-OFDM symbol was completely decomposed or the maximum symbol decomposition times were attained,thereby eliminated all-zero symbols and reduced the average symbol decomposition times.The performance of ASDST system was verified by theoretical analysis and Monte Carlo simulation.…”

    Improved SMC cardinality-balanced multi-Bernoulli forwardbackward smoothing track-before-detect algorithm by Jiazheng PEI, Yong HUANG, Yunlong DONG, Xiaolong CHEN

    Published 2019-08-01
    “…For the tracking problem of multiple maneuvering targets in radar observation,the sequential Monte-Carlo cardinality-balanced multi-Bernoulli track-before-detect (SMC-CBMeMBer-TBD) algorithm is inaccurate in the estimation of the number of targets and the precision of state estimation.An improved algorithm based on SMC-CBMeMBer forward backward smoothing track-before-detect algorithm was proposed.In the algorithm,the multi target particle swarm optimization (MOPSO) was added between the process of prediction and update,and the fitness function was set up based on the observation value to make the particle set move to the position of the larger posterior probability density distribution,and solve the particle poverty in the heavy sampling process.In the update step,the algorithm was used.Then the smoothing recursive method was added,and the arithmetic operation time was prolonged,but the number and the state estimation precision were improved.The simulation results show that compared with the CBMeMBer-TBD method,the proposed algorithm improves the accuracy of the estimation of the number of maneuvering targets and the accuracy of the target state estimation.…”

    Performance analysis of dual-hop PLC-FSO communication system by Shenghai CHEN, Xiaoqin YAN, Sai LI, Liang YANG

    Published 2021-10-01
    “…A dual-hop power line communication and free-space optical communication (PLC-FSO) system was proposed, where an amplify-and-forward (AF) relay was applied to help the signal transmission between the PLC link and the FSO link.More specifically, it was assumed that the PLC link was affected by both additive background noise and impulsive noise, and the channel fading followed log-normal distribution, while the fading induced by the atmospheric turbulence in the FSO link followed a Gamma-Gamma distribution, and the effect of pointing errors was also considered.Based on this model, closed-form expressions for the outage probability, bit error rate, and the channel capacity were derived.In addition, asymptotic analysis for the outage probability and BER, and upper bound expression for the channel capacity were presented.Finally, the accuracy of the analytical results was justified through Monte-Carlo simulations.The results show that the system outage probability decreases as the pointing error parameter increases and the smaller the PLC link impulse noise, the lower the bit error rate.The system capacity increases as the turbulence intensity decreases.…”
