pulse correlation

This paper derives the cross correlation function of baseband PAM ( Pulse Amplitude Modulation) signal, and shows that the cross correlation function includes timing information.

本文推导了基带PAM（脉冲幅度调制）信号的互相关函数，指出基带PAM信号的互相关函数中含有位同步信息，以此为依据得到了一种位同步检测算法。

The results show that the M2 factor depends on the pulse bandwidth ( or pulse duration), spatial correlation degree and average wavelength.

结果表明，M2因子受空间相关度，带宽（或脉冲宽度）和平均波长的影响。
