The Design Of Radio Channel Simulation Frame

Radio channel modeling and parameter estimating is important to design and research of the mobile communication system. The paper provides a visual modeling scheme using object-oriented technology, and does experiments for current impulse response models from model change to parameter design to graphical modeling. The frame is a visual solve for simulation analysis and transmission forecast of radio channels. On the one hand, the paper takes classic radio channels as independent objects and builds their graphical models, comes into being a visual universal model library. On the other hand, the paper deeply researches the principle of channel estimation algorithms, implements some typical algorithms and gives their graphical module encapsulation. Finally, the paper provides a design scheme of the channel simulation environment, and establishes a object-oriented channel simulation frame.The paper adopts object-oriented technology, deeply researches the modeling and parameter estimating technique of radio channels on MATLAB frame. At the present, object-oriented method have been in common use in software design, more in kernel design, but fewer in system simulation design. On the base of the visual channel model library and estimation algorithm library, the paper advances a integrative design scheme of radio channel simulation environment, which has some technical innovation and practical value. The frame which the paper constructes is integrative and easy to extensible, which is in favor of system function extension and upgrade.
