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.
