文档介绍：Abstract Bluetooth iS atechnology specification for low—~range radio 1inks between portable devices and any other devices that need to replace their wire connection. Bluetootb system provides voice and data serviees for both point—to—point and point—to—multi—point has a very bright cormlercial is important to owe the key technology of Bluetooth. The hardware design is important for Bluetooth baseband controller implements the functions of the Lower Link Controller,it iS a core aspect of Bluetooth hardware development. Because IP core iSreusable,it iS important for ICdesign,and italso will fast the development of 81uetooth hardware. The thesiS briefly introduces the background of the Bluetooth system, describes the detai ls of the Bluetooth hardware blocks,points out the key part and hard part of the hardware thesiS introduces the principles and process ofIPdesign,analyzes the architecture ofbaseband specification,gives out akind ofdivided hardware blocks blocks design scheme isalso given out. Based on the Bluetooth specification l。1,the thesis studies the detailS of the algorithms of the base band specifications,and designs blocks of error detection,data whitening,hop selection kernel andBhetooth security which include encryption and details of the blocks design are simulation shows that the blocks function well of the B1uetooth baseband. future development of thebaseband core iSpointed future of B1uetooth application and itS development iS alSO diSCUssed.
