    New realization scheme of pseudo-chaotic-based encoder and decoder for UWB communications by JIANG Guo-ping1, WAN Dong-dong1, XUE Long1

    Published 2005-01-01
    “…Chaos-modulation-based ultra wide band (UWB) communication was addressed.A new structure for the pseudo-chaotic encoder was presented,and some decoding schemes were also given accordingly.The performances of such decoding schemes were compared in the AWGN channel.Simulation results verify and demonstrate the effectiveness of the proposed method.…”

    Cooperative content downloading scheme based on D2D multicast communications by Lianxin YANG, Dan WU, Feng YUAN, Chao YUE, Qinxue FU

    Published 2020-11-01
    “…Aiming at the content downloading scenario in the network such as cellular network and vehicular network,a cooperative content downloading scheme based on device-to-device multicast communications was proposed to improve the content downloading performance.Such a scheme took advantage of the proximity feature of the content requesters and groups them into disjoint clusters.Firstly,the base station delivered the entire content to a cluster,and each content requester in a cluster downloaded a proportion of the entire content.Then,the content requesters took turns sharing their downloaded content with other content requesters in the same cluster.In this way,the additional resource consumption of content sharing in a cluster was shared by the content requesters in the cluster together.During this process,a pricing-based approach was proposed to motivate these content requesters to cooperate with each other.Such an approach only required the base station to maintain a content downloading price.Based on this,the joint issue of user clustering,link scheduling and power allocation was studied to minimize the total cost of content requesters.To obtain a superior solution with reductive complexity,a joint optimization algorithm was designed based on the coalition formation game.Numerical results show that compared with the traditional non-cooperative scheme,the total cost of content requesters was reduced by 37.15%.Under different numbers of content requesters and cellular users,the proposed scheme is both superior to other benchmark schemes.…”

    Advanced Optimization Algorithm Combining a Fuzzy Inference System for Vehicular Communications by Teguh Indra Bayu, Yung-Fa Huang, Jeang-Kuo Chen, Cheng-Hsiung Hsieh, Budhi Kristianto, Erwien Christianto, Suharyadi Suharyadi

    Published 2025-01-01
    “…This work introduces a novel optimization algorithm approach called the fuzzy inference reinforcement learning (FIRL) sequence for adaptive parameter configuration in cellular vehicle-to-everything (C-V2X) mode-4 communication networks. This innovative method combines a Sugeno-type fuzzy inference system (FIS) control system with a Q-learning reinforcement learning algorithm to optimize the PRR as the key metric for overall network performance. …”
