摘要
频移键控(FSK)是用不同频率的载波来传递数字信号,并用数字基带信号控制载波信号的频率。笔者提出了一种基于DDS(Digital Direct Synthesizer)技术的MFSK调制器的FPGA实现方案,并根据DSP开发工具DSP Builder的优点,采用VHDL文本与Simulink模型图相结合的方法进行了FPGA设计与仿真。仿真结果验证了设计的正确性及可行性。
The Frequency-Shift Keying(FSK) transmits the digital signal with different frequency carriers,and controls the frequency of carrier with the digital baseband signal.This paper proposes a scheme for implementation of MFSK modulator based on FPGA and DDS.According to the advantages of DSP Builder,the system is designed by utilizing VHDL and Simulink module.The correctness and feasibility of this design is verified by simulation result.
