摘要:

针对OFDM(正交频分复用)系统中对定时位置的高敏感性,设计了一种新的训练序列,基于此训练序列提出了OFDM新的同步算法,同时考虑了无线通信中多天线及多径问题。通过仿真可看出,算法消除了Schmidl算法的定时平台,并在多天线、多径信道中有着良好的表现。

关键词: OFDM, 训练序列, 同步算法

Abstract:

As for the high sensitivity to timing position of the OFDM (orthogonal frequency division multiplexing) system,this paper designs a new training sequence,based on which a new OFDM synchronization algorithm is proposed with in mind the multiple antenna and the multipath problems in wireless communication.Simulation shows that the proposed algorithm eliminates the Schmidl algorithm timing platform,and in the multiple antennas and the multipath channels it also has very good performance.

Key words: OFDM;training sequence;synchronization algorithm
