摘　　要：文中设计了一种基于软件无线电思想的数字FSK调制解调器系统。在掌握和分析诸多调制解调器的设计原理和方法之后,通过设置波形发生器,存储调制的正弦波,用这种较简单的方法实现了调制。并运用软件无线电的方法,提出了一种基于DFT原理的经典谱估计法,用以实现2FSK信号的解调方案,并在FPGA中设计实现。经验证方法可行。A digital FSK modem system based on software radio is designed. With mastery of and analysis on modem design principles and methods, a relatively simple method, through setting waveform generator and storing modulated sine wave, implements the modulation. Then by applying software radio methodology, a classic spectrum estimation based on DFT is proposed, which is used to implement the demodulation program of 2FSK signal. And the design is realized in FPGA, and the method is proved feasible.
