The Design of the Multi-Mode Modulation Module
Xin Qin · Journal of National University of Defense Technology · 2000
The design method of a multi mode modulation module based on PCI bus is presented and realized. Its foundation on which many types of middle frequency modulated signal are produced is the theory of orthogonal modulation and digital up converting. Another abstractive feature is that it connects the base band processing unit with PCI bus so that a flexible and powerful multi mode modulator can be made by combined this module with the general computer or commercial DSP board.
