It mainly includes two parts : the frequency offset caused by the difference of the mobile equipment ’ s transmitting frequency and the nodeb ’ s receiving frequency ; the frequency offset caused by the vehicle of the mobile equipment, which is called doppler shift. accurate frequency offset estimation and compensation is of importance for demodulation
它主要由兩部分構成:由於nodeb （基站）和移動臺晶振本振頻率的不同而產生頻偏;由於移動臺運動產生多普勒效應，引起的多普勒頻偏，在信號功率譜上表現為多普勒頻譜擴展（以後簡稱多普勒擴展） 。 -
Secondly, based on the analysis and simulations of the doppler time - shift for chirp - subpulse stepped frequency signal, this dissertation analyses the velocity compensation method for moving targets in chirp - subpulse stepped frequency signal, and presents a method for compensation of targets ’ velocity base on the least burst error rule
其次，本文對chirp子脈沖頻率步進信號的多普勒效應進行了分析和模擬，在此基礎上，分析了對其進行運動補償的思路，提出了採用最小脈組誤差準則進行運動補償的方法。
