In this paper, the radiolocation technique and principium of ofdm in the cell - communication system were introduced firstly, and sensitivity of ofdm system to synchronization was analyzed. then, two methods of timing synchronization based on the cyclic prefix and pilot sequence were introduced, and a novel timing synchronization method based on pilot sequence was presented, which provided a correlation peak with pulse shape
由於ofdm系統中的定時同步要求和無線定位中的測時測距在本質上是一致的，所以本文緊接著分析了基於循環前綴和導頻序列的兩種定時同步方法，並提出了一種新的基於導頻序列的具有脈沖形狀相關峰的定時同步方法。 -
The blind synchronization method based on cyclostationarity is firstly analyzed in the downlink. simulations of the method are carried out under different channel conditions. the performances of the method are analyzed, and then compared with the blind method based on the cyclic prefix of ofdm symbols, thus the validity of the method is proved
本文首先在下行鏈路中分析了基於ofdm信號的循環平穩特性的盲同步信息估計演算法，並在多種通道條件下進行了計算機模擬，對基於ofdm信號循環平穩特性的估計器的性能進行了分析，並與基於ofdm信號循環前綴的ml演算法的估計性能進行了比較，從而證明了提出演算法的有效性。
