| 摘 要： | OFDM系统面临的一个主要问题是对频率偏移的敏感性,频率偏移将导致子载波间干扰（ICI）的产生,从而大大降低系统性能。本文主要分析频偏存在时脉冲成形与子载波间干扰的关系,给出各种成形脉冲性能的评价标准,并提出在此标准下性能最佳的成形脉冲。

| Abstract: | A major problem for OFDM systems is the sensitivity of the frequency offset,and frequency offset will cause inter-carrier interference(ICI),which significantly reduces system performance.The paper analyzes the relationship between pulse shaping and the Inter-carrier interference when it exists frequency offset,proposes a variety evaluation criteria of pulse-shaping performance,and gives the optimum pulse-shaping under these standards. |

| Keywords: | orthogonal frequency division multiplexing pulse shaping inter-carrier interference |
