  1. In the synchronous techniques based pilot symbols, here propose a frequency offset estimating arithmetic using discrete pilot symbols. we pick up integer times sub - carrier frequency offset from the same ofdm symbol and estimate exact

    此外,在頻偏估計方面,推導出短訓練序列前後兩段時域符號間的關系,並利用此進行粗頻偏估計,使頻率偏移的估計范圍大大增加。
  2. Aimed at the characteristics that multi - carrier transmission is sensitive to frequency offset and require high synchronization performance, firstly multi - carrier ofdm technique is introduced, the influence of synchronization offset to ofdm system is analyzed and two kinds of typical synchronization methods are given based on pilot and cp in the paper

    針對多載波傳輸對載波偏移敏感,對同步要求高的特性,論文首先介紹了多載波ofdm技術,分析了同步偏移對ofdm系統性能的影響,給出了基於導頻和循環前綴的兩種典型的同步方法。
