A polyalphabetic cipher is any cipher based on substitution, using multiple substitution alphabets. The Vigenère cipher is probably the best-known example of a polyalphabetic cipher, though it is a simplified special case.Polyalphabetic substitution ciphers are useful because the are less easily broken by frequency analysis, however if an attacker knows for instance that the message has a period n, then he simply can individually frequency analyze each cipher alphabet. The number of letters encrypted before a polyalphabetic substitution cipher returns to its first cipher alphabet is called its period. The larger the period, the stronger the cipher. Of course, this method of encryption is certainly not secure by any definition and should not be applied to any real-life scenarios.

在数字信号的基带传输过程中，信息传输速率在满足香农公式的条件下还极大地受到码间干扰的限制(It is also limited by intersymbol interference when transmission speed of code accord with Shannon expressions in the course of baseband transmission of digital signal.)

数学建模仿真maple的教程，很多人都用matlab进行科学研究，其实数值计算功能最强大的是maple，几个语句就能实现matlab很难实现的数学运算，这本书很经典，最总要的是Word版本，很方便移植到程序上验证的哦(Mathematical modeling and simulation maple tutorial, many people are using matlab for scientific research, in fact, the most powerful numerical calculation is maple, several statements can be very difficult to achieve matlab mathematical operations, this book is classic, the best always the Word version, it is easy to transplant procedure validation Oh)

MATLAB与通信仿真，有大量实例，非常有参考价值，文件为pdg格式，需用超星阅览器打开(MATLAB simulation and communications, has a large number of examples, a very valuable reference document for the PDG format, need to open browser Chaoxing)
