摘　　要：本文针对突发信道,根据性能指标要求,研究分析了几种经典校频算法在该突发信道中的性能差异,得出各种算法在该指标下均不能达到预期性能,基于此本文设计出一种新的校频思路,同时针对新算法对帧结构重新做合理修改,进而满足该突发信道下的性能指标要求。In line with the performance requirement,this paper analyses the performance difference of several classical frequency calibration algorithms in the burst channel. The result shows the desired performance cannot be reached with each above mentioned algorithm. Therefore,a new frequency calibration method is put forward which may meet the performance requirement of the burst channel after reasonable modifications of frame structure are made in accordance with the new method.
