扩频通信是现代通信系统中新的通信方式,它具有较强的抗干扰、抗衰落和抗多径性能,频谱利用率高。扩频通信是通信的一个重要分支和发展方向,是扩频技术与通信相结合的产物。扩频通信的强抗干扰性、低截获性、良好的抗多路径干扰性和安全性等特点,使它的应用迅速从军用扩展到民用通信中,它的易于实现码分多址的特点,使它能与第三代移动通信系统完美结合,不但完善了中国移动的在3G竞争上的核心技术的不足,也为扩频技术的进一步深化提供了更广泛的领域,发展前景极为广阔。
Spread spectrum communication is a new communication method in modern communication systems. It has strong anti-interference, anti-fading and anti-multipath performance and high spectral efficiency. Spread spectrum communication is an important branch of communication and development direction, is the product of combining spread spectrum technology and communication. The strong anti-jamming, low interception, good anti-multipath interference and security features of spread spectrum communication make its application expand rapidly from military to civil communication. It is easy to realize the characteristics of code division multiple access, Making it the perfect combination with the third generation of mobile communication system, which not only improves the shortcomings of China Mobile’s core technology in the 3G competition, but also provides a broader field for the further deepening of the spread spectrum technology. The development prospect is extremely broad.
