摘要
本文利用Ｃｈｒｅｓｔｏｎｓｏｎ函数和实多值Ｗａｌｓｈ函数映射出一种新的函数，称为实多值多项式函数。这个函数可用于三值ＣＤＭＡ移动通信系统中对三值信号进行扩频和正交调制。本文进一步讨论了利用多项式函数进行三值扩频和正交调制的方法。
In this paper new functions which are cAlled polynomial functions are introduced from the Chrestenson functions and the real multiple_valued Walsh functions.The new functions may be applicable to spread spectrum and orthogonal modulation of ternary information in the ternary CDMA mobile communications system.The methods of ternary spread spectrum and orthogonal modulation are discussed.
