The Application Research Of Bluetooth Technology In Communication Between Opposite Moving Terminals

In the practical satellites communication system carried by vehicles, the opposite moving between antenna and communication equipement will happen. If the two terminals are connected by cables, the cables will be enwinded. Bluetooth, as a short distance wireless communication technoligy, is a reasonable scheme in this condition. In this thesis, the basic theory and composing of Bluetooth technology are introduced; 4 important Bluetooth protocols (L2CAP, HCI, RFCOMM and SDP) are analysized; the Bluetooth serial port application profile is expatitated on the base of protocols. Then the hardware design of Bluetooth adapter is put forward; the hardware and software of serial ports among modules of Bluetooth adapter are designed and realized; the BER testing software of Bluetooth communication system based on the arithmetic of m-sequence generation is developed. In the end, the BER of Bluetooth technology between opposite moving terminals with and without shelters between them is tested and the conclusion is given. From the conclusion, Bluetooth technology can satisfied the practical needs of this project. The Bluetooth adapter system is unique and provided a test platform of software and hardware for the advanced exploiture of wireless communication system based on Bluetooth.
