摘要
软件无线电是无线通信技术发展的一次飞跃。通过软件无线电台这个通用的系统平台能实现传统无线通信的各种功能。文章研究了基于软件无线电技术的直接序列扩频通信系统的数学模型并进行了系统仿真。仿真证明软件无线电技术对扩展频谱系统的改造的有效性。
Software radio is a leap in the development of wireless communication technology.The software radio which is concerned as a generic system platform can realize various functions of wireless communication.In this paper,we studied on the mathematic model of direct sequence spread spectrum communication system which is based on the Software Radio Technology and made the system simulation.Simulation proves that the software radio technology is fruitful in transformation of spread spectrum system.
