two-dimensional autocorrelation

Two statistical quantities are proposed in this paper, that is Q and R, Q is called the exponent of dynamical autocorrelation factor, and R is called the exponent of dynamical cross_correlation factor.

定义了两个新的统计量，分别记为Q和R，Q称为动力学自相关因子指数，R称为动力学互相关因子指数。

Depending on the autocorrelation property of a judiciously chosen training sequence, a redundance-included demodulation template ( RDT) can be extracted from the received signal by separating, shifting and realigning two connected portions in the observation window.

通过引入一个具有特殊自相关特性的训练序列，可以将一个符号长度的信号中两个相连接的部分，进行拆分、移位并重置，最后重建为一个有冗余的解调模板（RDT）。
