基于CORDIC算法2FSK调制器的FPGA设计

Design of 2FSK Modulator Based on CORDIC Algorithm and FPGA

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。提出一种基于流水线CORDIC算法的2FSK调制器的FPGA实现方案,可有效地节省FPGA的硬件资源,提高运算速度。最后,给出该方案的硬件测试结果,验证了设计的正确性。

The frequency-shift keying（FSK） transmits the digital signal with different frequency carrier,and controls the frequency of carrier with the digital basedand signal.The implementation scheme of 2FSK modulator based on pipeline CORDIC algorithm and FPGA is porposed.It can save the hardware resources and improve the operating speed efficiently.The design was verified by the practical testing result.
