The WiMAX Space Connector Engineering's Research And The Simulation Realize

WiMAX is one kind of emerging wide band wireless access technical standard. It is an technology of wireless metropolitan area network (WMAN), proposed one kind of space connector standard aims at the microwave and the millimeter wave frequency band, was considered important means that is solves the wide band metropolitan area network construction "the last kilometer".The thesis has studied the WiMAX MAC level system structure, and based on the IEEE802.16 code requirement, has conducted the research to the gathering sublayer, has given the MAC level flow design, and has carried on the explanation to the QoS thought. The thesis has studied MAN-OFDM and the MAN-OFDMA technology emphasily in WiMAX physical level four kind of structure, refers to the IEEE802.16 tetherless access standard, the algorithm which to the WiMAX system in the synchronization, the range finder, the channel estimated has conducted the research separately, has improved algorithm on the original algorithmic analysis comparison foundation, and has confirmed the improvement algorithm performance after the simulation.
