蓝牙跳频算法的改进与蓝牙家庭网络的研究

硕士学位论文AbstractWith the rapid popularization of PC and Internet in the home,and improvementof the intelligentized degree of information household appliances,HomeNet,especially simple,flexible and robust HomeNet is getting more and more attention.Asa short-range wireless communication technology,Bluetooth is one of the bestsolution to low-rate wireless HomeNet connection.Working at the opening 2.4GHz ISM band which is free to be accessed,Bluetooth devices will be easily interfered with by other systems.To induce the RFinterference from other systems by the greatest degree,Bluetooth uses the fastfrequency hopping technology.The hop selection algorithm is introduced in this paper.And to improve the performance of anti-interference,an improved adaptive frequencyhopping scheme is suggested on the basis of original algorithm.To compare theanti-interference performance between the original and improved system,systememulation and performance analysis is implemented by using C language and Matlab.The result of emulation and analysis shows that the improved scheme put forward bythe paper greatly enhances the system's anti-interference performance.The other part of this paper discusses the research and realization of theBluetooth-based HomeNet,including how to realize long-distance control to theinformation household appliances through Internet,and how the PC or portablecomputer in the HomeNet accesses Internet through Bluetooth gateway.Therealization of Bluetooth gateway is emphasized.Commencing on the Bluetoothapplication profile-LAN Access Profile,the paper discusses until the implement ofBluetooth protocols and high layer Bluetooth application programming to the finalrealization of LAN Access Profile in detail.Keywords:Bluetooth,HomeNet,Bluetooth gateway,LAN Access,hopping algorithm,adaptive.0
