摘要
讨论了基于FPGA上如何实现二进制相位编码信号(BPSK)的频率盲估计算法。实现在没有接收信号先验知识的情况下,对BPSK信号的信号载频进行估计。分析了实现频率估计的原理,通过从接收信号中提取载波信息,并转化到频域上进行计算估计。本文列出了在FPGA上实现的模块流程图,最后通过FPGA的时序仿真来验证频率估计的有效性。
The article discusses how to implement the arithmetic of frequency estimation of BPSK based on FPGA and it implements frequency estimation of BPSK without pre-knowledge.The principles are analyzed,and the information of carrier wave which is got from the receiving signal is transformed from the parameter of time into frequency to calculate the frequency estimation.Then the FPGA implement flowcharts are listed.Finally,the timing simulation by FPGA makes sure the validaty of frequency estimation.
