摘要
本文采用直接数字频率合成技术(DDS),根据通信系统中数字调制方式的理论基础,利用FPGA的DSP开发工具DSP Builder对基本DDS建模,并由该DDS模块实现数字调制信号2ASK、2FSK、2PSK,同时用ModelSim和QuartusII进行功能仿真和时序仿真,仿真结果表明设计方法的正确性和实用性。
This paper makes use of Direct Digital Synthesizer(DDS) and takes the digital modulation mode in the communica- tion system as its theoretical basis, the basic DDS is designed based on DSP Builder of FPGA, and the Digital modulation signal of 2ASK,2FSK,2PSK is implemented by using the DDS module. Simultaneity, the Digital modulation signal's function simulation and timing simulation with ModelSim and QuartusII shows the correctness and practicability.
