Self Interference Elimination Scheme for Enhancing Coverage Equipment of Power Wireless Private Network
摘要
Abstract
The power wireless private network is an important communication network that carries collaborative and interactive information between the source,grid,load,and storage of a new type of power system.However,in practical applications,existing wireless power private networks have coverage blind spots in areas such as basements,dense urban areas,and shaded areas of buildings,making it impossible to achieve full coverage.As a wireless signal relay device,a repeater can improve network coverage.However,the repeater based on full duplex communication has serious self interference problems,which greatly affect its communication performance.This paper proposes a full duplex self interference elimination scheme suitable for power wireless private network repeaters,which can reduce the self interference of full duplex transceivers in power wireless private networks to the ground noise level.Compared to the half duplex mode,this scheme doubles the spectral efficiency while only losing about 1 dB in the signal-to-noise ratio of the received signal,meeting the requirements of self interference suppression for power wireless private network repeaters,effectively expanding network coverage,and providing strong communication support for the construction of a new type of power system.关键词
