The computation burden of the quadrature sampling and pulse compression is huge when the data rate is high and the time bandwidth product is not small.
在高数据采样率，特别是大时宽带宽积条件下，时域的数字正交采样和脉冲压缩包含大量的乘加运算。

The results indicated that one of the two quadrature components of light field evolves periodically with time and can be squeezed, and the system parameters influence the squeezing depth;
结果表明：光场的两正交分量的涨落均可压缩，压缩程度受系统参数的影响，并且随时间呈周期性变化；

At the same time, we refrain mirror frequency effectively with the method of digital quadrature modulation (DQM).
