| | A method is presented in this paper which extends the copy theory of Walsh function from binary and multi system to hybrid carry system.The copy theory of generalized Walsh function for hybrid carry system is first discussed in detail,and then analyzed mathematically.It is of importance for deep research of signal copy theory. | | 本文把二进制、多进制沃尔什函数的复制生成理论推广到了混合进制情形 ,给出了混合进制广义沃尔什函数的复制生成方法 ,并对复制生成方法进行了数学分析 .它对信号的复制生成理论的深入研究有一定的理论价值 | | 文摘来源 | | Copy theory of signals is a theory that studies how to generate signals based on the copy method. Its main researches include the copy property of signals, generation principle and property by different copy information and copy modes. At first, this paper accounts the copy theory of signals briefly, and then emphasizes the introduction to a new catch method of pseudo\|random codes. | | 信号的复制生成理论是基于复制方法生成信号的理论 ,它主要研究信号 (序列 )的复制特性、在不同的复制信息和复制方式下信号 (序列 )的生成原理和性质。在简要介绍信号的复制生成理论的基础上 ,着重介绍了利用复制理论提出的一种新的伪随机码捕捉方法。 | | 文摘来源 | | In this paper,at first,copy analytical theory of signal is presented.At the same time,the method of copy modulation and demodulation and its property are discussed.Then on the condition of white noise,the capabilities of three different demodulation methods are analyzed by computer simulation.Finally,on the condition of initial phase or frequency shift,the properties of the matching demodulation and characteristic demodulation are analysed by computer simulation.The important conclusions are drawn. | | 首先介绍了信号的复制分析理论和复制调制 解调的方法及特点 ,然后通过计算机仿真 ,对三种不同的解调方法在白噪声下的性能进行了分析 ,对匹配解调法和特性解调法在有初相和频差条件下的性能进行了仿真比较。 | | 文摘来源 | |   | | << 更多相关文摘 |
