FSK信号的非相干数字解调技术

Noncoherent Digital Demodulation Technology of FSK Signals

频移键控(FSK)信号在通信系统的广泛应用,使其解调技术也成为一种核心技术。本文介绍了一种全新的基于FPGA技术的非相干数字解调方式,并借助硬件描述语言VerilogHDL语言,使设计具备了很好的移植性、可编程性和一致性。

As a kernel method,FSK demodulation technique is widely applied in communication systems. In this paper, a novel demodulation technique based on FPGA is presented, which employs the noncoherent digital demodulation. Making use of the Verilog Hardware Designing Language (Verilog HDL), this technique possesses many virtues, such as good transplantability, programmability and consistency.
