| Abstract: | The module for BPSK modulating signal＆#39;s carrier frequency estimation is realized on the platform of FPGA, based on the BPSK modulating signal＆#39;s generating mechanism and the principle of the square of frequency doubling method. The function of carrier frequency estimation module is simulated in the environment of Modelsim. The effectiveness of estimating BPSK modulated signal by square doubling method is verified. The simulation results show that the BPSK signal carrier frequency estimation module has high accuracy and simple realization, and certain practical application value. |
