摘要
高速窄带电力线通信(HNPLC)多用户实时动态频谱管理(DSM)是确保HNPLC满足泛在感知终端接入性能需求的极佳选择。采用子载波分组和实时选取一种最优调制方式的方法,既显著提升了多用户传输的可靠性和传输速率,又有效减少了信令和资源开销。线上实验证明,所述HNPLC多用户实时DSM使系统的传输速率提升至传统方法的5倍多,可满足实用化需求。
High-speed Narrowband Power Line Communication(HNPLC)multiuser real-time Dynamic Spectrum Management(DSM)is an excellent choice to ensure the access performance requirements of the ubiquitous sensing terminals.Subcarrier grouping and real-time selection of a unique modulation type for all terminals not only ensure the reliability and transmission rate of multiuser transmission,but also reduce the resource and signaling overhead.Online experiments show that the HNPLC multiuser real-time DSM improves the transmission rate by about 5 times when compared with the traditional method,which completely meets the practical requirements.
