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
