内容記述 |
In underwater acoustic communication (UAC), very long delay waves are caused by reflection from water surfaces and bottoms and obstacles. Their waves interfere with desired waves and induce strong multipath interference. Use of a guard interval (GI) is effective for channel compensation inOFDM.However, a GI tends to be long in shallow-water environment because a guard time is determined by a delay time ofmultipath. A long GI produces a very longOFDMframe in several seconds, which is disadvantageous to a response speed of communication. This paper presents a method of keeping good communication performance even for a short GI. We discuss influence of intercarrier interference (ICI) in OFDM demodulation and propose a method of data selective rake reception (DSRake).The effectiveness of the proposed method is discussed by received signal distribution and confirmed by simulation results. |
