环路定时 meaning in Chinese

lootiming

Design a kind of sub - optimum digital prefilter . through the simulation of timing recovery loop which is n ' t added prefilter and which is added prefilter , discuss the convergence characteristic and compare the relation between timing jitter and signal to noise ratio , the relation between timing jitter and noise bandwidth of loop , the relation between symbol error ratio and signal to noise ratio
通过对加预滤波器后的定时恢复环的仿真，讨论了环路的收敛情况，比较了所设计的数字预滤波器和无预滤波器时环路定时抖动与信噪比、定时抖动与环路噪声带宽、误码率与信噪比的数量关系，证实所设计的数字预滤波器对减少定时抖动非常有效。
