摘要
直序扩谱系统中,扩谱增益的提高与数据速率的提高存在一定的矛盾.分析了伪随机码与正交码的特性,提出了一种复合码编码扩谱系统;详细介绍了该系统的数据结构和系统构成;并在此基础上,设计完成了一种扩谱系统,完成了768 kbit高速图像压缩数据的传输.
In the direct-spread-spectrum-system, it is difficult to increase the spread-spectrum gain and the data rate together. The paper analyses the property of pseudo-noise code and the orthogonal-code, proposes the compound-coding spread spectrum system, and introduces the data structures and the components of the system in detail. Based on these, the authors designed and accomplished a kind of spread-spectrum system, and transmited the compressed image data at a high data rate of 768 kbit.
