| 摘要: |
| 分析了多制式调制的原理, 提出并实现了一种基于 PCI 总线的多制式调制模块的设计方案。它采用正交调制与数字上变频方法, 可以生成多种中频调制信号。它的另一个特点是将基带处理单元用 PCI 总线隔离开来, 可以结合通用计算机或商用 DSP 处理模块, 构成一结构灵活而又具有实时处理能力的多制式调制系统。 |

| Abstract: |
| 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. |
