摘要
给出了构造有限域上的一类正交变换的具体方法,该变换运算简便且有快速算法,与普通Walsh变换相比,具有压缩输出数据的功能,可用于同步码分多址通信系统中。
Concrete method about constructing a class of orthogonal transform in finite field is given. These transforms that are calculated easily have fast algorithm and possess a function of compression outgoing data, compared with generic Walsh Transform. They can be applied to Synchronous Code Division Multiple Access.
