数字16进制正交扩频收端的设计

First, this paper proceeds from the development of spread of frequency telecommunications, and briefly introduces the basic knowledges such as concepts, excellence,characteristics, the application and development direction of spread of frequency is also includes. Then I specificly expounds on the elements of the technology of spread of frequency, such as Walsh function and m sequence, which is the base of the paper. Next I introduced QuartusⅡand VHDL. They are the programming language and simulation platform. And the last is the realization contents of the design of hex orthogonal spread of frequency system’sink with some explanation of the simulation.
