The performance of synchronization tracking using pilot is analyzed, followed by a numerical method to determine the optimal lock loop parameters to minimize average bit error rate ( BER ). 分析了利用导频同步跟踪的性能,以及提出了一个数值方法确定最优环路参数以最小化误码率。
The locknut is rotated to lock the spring chuck, so as to clamp a drill bit which is enabled to rotate along with the spindle to carry out the drilling processing. 通过转动锁紧螺母锁紧弹簧夹头从而夹紧钻头,使钻头跟随主轴旋转进行钻削加工。
