Design and implementation of Costas loop based-on FPGA

LIN Hai Du GAO Qiang (School of Electrical Engineering,Harbin Institute of Technology,Harbin 150001,China)  
This paper introduced the problems of the traditional analog Costas loop.The operating principle of the Costas Loop is introduced and the discrete time model of the Costas loop is setup by means of the transform between continuous time domain and discrete time domain.According to this model,the parameters and circuit of each module are designed.The Costas loop is im- plementod on the FPGA and its RTL schematic is presented.
