摘要
AWG在数字通信系统中的地位非常重要,其应用包括调制解调、上下变频、软件无线电等.提出了利用FPGA芯片,采用直接数字频率合成技术,完成对AWG的设计与实现.在架构设计上,采用自上而下的模块化设计方法,系统架构清晰,并具有较好的可移植性和重用性.经过设计和仿真测试,波形输出达到了技术要求.系统具有控制灵活、高速、性能良好、资源利用率低等优点.
AWG plays an important role in digital communication systems. Typical applica tion of AWG includes modulation/demodulation, up/down converter, software radio, etc. Using FPGA chip, the design and implementation of the AWG are fulfilled with direct digital frequency synthesis technology. The way of design of the structure is up to down modularization, the system structure is clear, at the same time it has better portability and reusability. The simulation test indicates that the waveform output reaches the technological requirement. And the system has a flexible controllability, high speed, better capability, less device utilization and so on.
