  author={Lu Qi-zhong},
In this paper,a new FPGA-based method of designing digital IF receiver is proposed.In this method,the peak of frequency is first detected by FFT algorithm,then a band-pass filtering and a quadrature transform are done.After this,the instantaneous phase of the transformed signal is calculated by CORDIC algorithm.Finally the frequency is estimated in a more precise way by the phase differential method.The outline of the design and its realization in FPGA are described in detail.Hardware… CONTINUE READING
