About time and ratio of return to work and housework, the EET group was higher and earlier than no EET (N-EET) group.

而EET组与对照组比较，其复工率、复工时间、恢复家务的时间和比率均比之多和早，二者之间差别有统计学意义。

The problem above can be resolved by the blind synchronization algorithm. The theoretic analysis and experimental results show that the approach can work well on the lower S/N ratio input signals.

理论分析及计算机仿真结果表明，该算法在低信噪比条件下可实现DS/SS信号的盲同步及PN码序列的精确估计。
