1、 石家庄经济学院 本科生毕业设计（论文） 外文翻译 题 目 蓝牙 语音信号传输系统设计与仿真实现 姓 名 郭小林 学 号 407109060213 学 院 信息工程学院 专 业 通信工程 指导教师 边群玲 Bluetooth Human is entering the digital network information age, a great number of digital communication and data transfer is achieved through the cable. These cables connected to these connectors
2、in shape, size and pin number of photogenic match through a variety of connectors and a variety of devices. Wired connection of digital equipment bring a lot of inconvenience for people to connect to networks anytime and anywhere. The development of wireless communication link technology, liberating
3、 people from the shackles of a wired connection, has become a trend. The greatest feature of the Information Age is more convenient and rapid information dissemination, based on this point, technical staff is also working to develop more excellent information and data transmission. Bluetooth technol
4、ogy (Bluetooth) is a short-range wireless communication open technology which launched in 1998 by Ericsson (Ericsson), Nokia (NOKIA), Toshiba (TOSHIBA), International Business Machines (IBM) and Intel (INTEL) and other companies jointly. It Intends for portable or fixed electronic devices replace th
5、e use of cables or connections such as cable connections. Its main feature is a powerful, low power consumption, transmission reliability, versatility, low cost, and easy to use. We can use in the office, home, travel and in the laboratory, without any electronic devices in the special cable and con
6、nector layout. Bluetooth devices can form through a micro-network, net of any Bluetooth transceiver can communicate with the device signal, and this connection does not require complex software support. Cast aside the shackles of the traditional connection, completely carefree days of fun, Bluetooth
7、 promises to give us enough to make spirits. Bluetooth, for the entire IT industry, has more than just a simple technology that has become a concept. Bluetooth technology is the founder of Swedens Ericsson, already as early as 1994 its research and development. February 1998, Ericsson, Nokia, IBM, T
8、oshiba and Intel formed a five multinational special interest group (SIG, Special Interest Group), aims to create a global common standard short-range wireless communication technology, now Bluetooth technology. Bluetooth name from the 10th century Danish King Harald Blatand-translated as Harold Blu
9、etooth (because he was very fond of eating blueberries, so every day with a blue tooth), he had a unified Europe over Norway, Sweden and Denmark. The high will be named after him, is to express a unified industry standard Bluetooth technology to make coordination between different industrial areas,
10、good communication with each other to meaning. Bluetooth applications for work permits without the 2.4GHz ISM band, based on time division multiplexing and frequency hopping principle, the combination of circuit switching and packet switching is suitable for voice transmission and data transmission. Currently, Bluetooth products have been widely used in mobile communications, computer and peripheral equipment, automotive, industrial controls, appliances, office applications, e-commerce, medical fitness and other fields.
