为了解决实际工程中信号被干扰的问题，增强纠检错能力，并提高保密性，提出了一 种结合了RS纠错编码和Walsh变换的软扩频技术。通过对RS纠错编码产生和利用Walsh函数与 复合码技术的Walsh变换方法的研究，以及和一般直扩频的比较，利用Matlab仿真阐述了软 扩频技术的优势，并介绍了这种软扩频技术在实际工程中的应用。

Soft spectrum spreading technique combining RS error-correction coding and Walsh transforming

In order to solve signal interference in practical engineering and improve err or-correction as well as encryption capability, a soft spectrum spread ing technique combining RS error-correction coding and Walsh transform is propos ed. Through RS error-correction codes generation, Walsh transform method researc h with help of Walsh function and composite coding, and comparison with conventi onal direct spectrum spreading, advantage of soft spectrum spreading technique is discussed based on Matlab simulation. Furthermore, practical engineering is a lso introduced.
