| 摘 要： | BPSK(二进制相移键控)信号相位突变点的检测是BPSK信号处理的一个重要特征,尤其在低信噪比情况下,对相位突变点的检测更加困难。文中利用Harr小波对含噪声的BPSK信号进行小波变换,利用BPSK信号在Harr小波变换下的特性很容易从小波系数中得到BPSK信号的基带信号。

| Abstract: | The detection of the sudden change points of the BPSK signal is one of the most important items in BPSK signal processing.It becomes more difficult in the low signal to noise ratio situation especially.In this paper,we derive the special properties of the BPSK signal under Harr wavelet transform first,then byusing these properties it can be gotten the base-band digital signal of the BPSK signal contaminated by a Gaussian white noise can be extracted. |
