| 摘 要： | 通过使用最大似然估计算法,对二相移相键控（2PSK）信号在高斯白噪声条件下的信噪比估计进行了研究,推导出信号功率、噪声功率的估计公式,依据该公式构建了2PSK的信噪比估计仿真模型,并在Matlab中进行了仿真计算,仿真结果表明在数据长度达到2000个左右时,信噪比的估计性能较好。

| Abstract: | By using maximum likelihood estimation algorithm,SNR estimation of 2PSK signal in Gaussian white noise is studied,and the formula of signal,noise power estimation is derived based on the formula,the SNR estimation simulation model of 2PSK is built,and a MATLAB simulation is carried out.Simulation results show that the ratio of the estimated signal to noise has a better performance when the data length is about 2,000. |
