摘　　要：根据BPSK调制信号调制机理和平方倍频法原理,在FPGA平台上设计实现了BPSK调制信号载波频率估计单元。利用ModelSim仿真环境对载频估计功能进行仿真,验证了平方倍频法对BPSK信号进行载波信号估计的有效性。仿真表明基于FPGA的BPSK信号载频估计单元,有较高的估计精度,且实现原理简单,有一定的实际应用价值。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.
