摘要
介绍了软扩频系统的基本原理和编码 ,实现框图 ,分析比较了软扩频系统和一般直扩频系统在给定的加性高斯白噪声信道条件下的误比特性能。结果表明 ,软扩频技术的应用 。
This paper introduces the principle and coding of tamed spread spectrum system, the error bit ratios of tamed spread spectrum systems and general direct sequence spread spectrum systems are analyzed and compared. The result proves that the error bit ability of the system can be raised when the tamed spread spectrum is adopted.
