摘　　要：基于对早-晚门同步技术的研究分析,在单片现场可编程门阵列(FPGA)上实现了外部输入码元的本地时钟同步,产生了本地同步载波信号,并在此基础上完成对外部输入码元的相干二进制相移键控调制。仿真结果表明,设计的模块能输出较好的BPSK信号,满足实际工程需要。The principle of early-late gate synchronization technique is analyzed. Synchronization for external symbols is achieved in a single chip of FPGA, and the local coherent carrier is generated. On this base, coher- ent BPSK modulation of external symbols is realized. Simulation result shows that the designed module can output BPSK signal and meets the requirement of engineering application.
