一种基于累加支路辅助的上面级跟踪切换方案
Scheme of upper-stage tracking switch based on accumulative branch
摘要
Abstract
In order to meet the need of tracking a huge number of data in the downlink of upper-stage on rocket, a novel information frame format for upper-stage was designed based on isochronous insertion. The tracking scheme in this frame format was described as follows: the output of the accumulative branch on second-order loop filter is used to aid the switch between Delay Locked Loop and Bit-synchronization Loop. The performance of this scheme is simulated by Matlab based on the educed scaling factor. The simulation results illustrate that the switch scheme realized smooth transitions with high performance.关键词
