随着用户的剧增,现有的无线资源已经难以为继.因此,电力线通信(PLC)的重新启用引起了各大研究单位及工业界的关注.PLC由于信道环境复杂,现有处理方案复杂度及成本较高,因而导致其发展缓慢.其中针对脉冲噪声的研究工作最为广泛,如何在低成本情况下针对脉冲噪声实现数据传输的鲁棒性尤为重要.该文首先介绍PLC环境中几种主流噪声以及分类,而后描述具有低成本低复杂度的差分混沌键控(DCSK)及多元DCSK(MDCSK)调制技术.分别介绍与分析该系统在PLC中的特性,以及针对各种脉冲噪声种类存在的优势以及改进方式.其次该文将介绍一些相关编码调制新方案以便于提高带限环境下的传输质量.结果表明这些优化工作显著地改善了系统性能,针对PLC整体信道特性系统参数的调制及编码调制传输优化方案将成为未来工作的研究热点.
Survey on Optimised Design of Robust Chaotic Transmission Systems for Impulsive Noise under Power Line Communication Channels
With the drastic increase in the number of users,the existing wireless resources have become unsustainable.Therefore,the reactivation of Power Line Communication(PLC)has attracted the attention of major research institutes and industries.The development of PLC has been slow due to the complexity of the channel environment and the complexity and high cost of existing processing solutions.The most extensive work has been done on impulse noise,and it is particularly important to achieve robustness of data transmission against impulse noise at low cost.Firstly,the mainstream noise in PLC environment and its classification are introduced in this paper,and then the Differential Chaos Shift Keying(DCSK)and M-ary DCSK(MDCSK)modulation techniques with low cost and low complexity are described.The characteristics of this system in PLCs are presented and analysed,as well as the advantages and improvements that exist for various types of impulse noise.Secondly,some relevant new coding and modulation schemes are introduced in order to improve the transmission quality in band-limited environments.The results show that these optimisations significantly improve the system performance.Subsequently,modulation and coded modulation transmission optimisation schemes for PLC overall channel characteristics system parameters will be a hot topic for future work.
