由于回波信号的估值直接利用二进数据码合成，使运算量比传统的算法减少了3 ~ 5倍。

Since the estimated echo signals are directly derived from the binary data code, the amount of manipulation is reduced by a factor of 3-5 compared with conventional manipulation.

这种算法是在交叉块匹配法的基础上提出的，并且可用于提高其它几种快速块匹配算法的准确率。该算法运算量较小，运动估值的准确率较高。

It is based on the cross search algorithm, capable of improving the accuracy of some other quick matching algorithms, of high accuracy of motion estimation, and requires fewer calculations.
