Review of Interference Mitigation Techniques for White Space Networks
2019 IEEE 2ND WIRELESS AFRICA CONFERENCE (WAC)(2019)
摘要
An important challenge to guarantee the successful operation of white space networks based on spectrum sharing, in a heterogeneous wireless network environment, is mitigation of interference. Interference mitigation (IM) is a term used to describe the techniques applied to minimize interference between networks operating in the same or adjacent spectrum bands. This paper will present a review of existing interference mitigation techniques with the aim of improving co-existence between spectrum sharing white space networks; it will also improve network quality of service. Furthermore, the paper will provide a detailed description of some of the recent IM techniques developed for TV white space networks, involving the geo-location spectrum database (GLSD) and reconfigurable radio devices.
