基于FPGA的2FSK解调的优化设计和实现

Optimized Design and Implementation of 2FSK Demodulation Based on FPGA

频移键控(FSK)信号广泛应用在通信系统中,软件无线电的高速发展,为FSK解调算法的硬件实现提供了便利。基于FPGA技术,采用VHDL实现FSK解调算法,结合一些先进的EDA工具软件,大大缩短了设计周期,具有较高的灵活性、可编程性和开放性。

FSK signal is widely applied in communication system, with the rapid development of software radio, the hardware implementation of FSK demodulation becomes more convenient. Based on FPGA, the implementation of FSK demodulation algorithm by using VHDL and combining with some advanced EDA tools can significantly shorten the design cycle. This method has many advantages, such as high flexibility, programmability and openness.
