As well known, noise is one of mainobjects of signals processing. However, many kindsof noises are affecting widely on mobile communica-tion along with enlarging mobile networks and rapidlyincreasing application range of multimedia commu-nication. The noises include 1/f noise; burst noise;multichannel noise; thermal and shot noise etc., allof which here are called "multi-noise (MN)" and atthe same time, the signals affected by "multi-noise"is called "multi-noise signals". The article firstly ana-lyzes some disturbance factors of multi-noise that af-fects multimedia flow. Then, it describes briefly hi-erarchical fuzzy control (HFC) technology and its ap-plication procedure for online identification and con-trolling multi-noise signals in mobile multimedia com-munication networks. Lastly, how to make a specialhierarchical fuzzy control program is also discussed.With different test examples, the article demonstratesthe ability of hierarchical fuzzy control to identifyflow states and control signal distortion in multime-dia communication. The hierarchical fuzzy controland hierarchical fuzzy control programs provide anadvanced efficient tool for supervising the distributedstates of multi-noise and movement characteristics ofmulti-noise signals in mobile multimedia communica-tion.
