无线扩频通信机研究

Research of Wireless Spread-Spectrum Communicator

扩频是源于军事保密而发展起来的一种数字编码技术,随着技术与器件的发展,扩频技术正从军用通信领域进入到民用通信领域。本文介绍了一种利用扩频通信技术实现的工作在2.4～2.4835GHz工业、科学、医学(ISM)频段的点对点数字微波电台,阐述了扩频通信技术的有关理论,并介绍了实现该系统的硬件和控制软件。

Spread spectrum is a digital coding technique initially developed for military secret. With the progress of technique and devices,spread spectrum system is entering into civil communications from military communications. This paper presents a design of point-to-point digital microwave radio that operates in the 2. 4 to 2. 4835GHz Industrial,Scientific,and Medical (ISM) frequency band and uses the spread-spectrum communication technology. Moreover,the paper introduces also hardware and control software of the system.
