| 摘 要： | 针对传统的基于训练序列的OFDM符号定时同步算法的缺陷，提出一种新的基于PN训练序列的符号定时算法。该算法通过重新设计训练序列，并加入PN序列，有效地克服了传统算法的缺陷。仿真结果表明，该算法在AWGN信道下能准确的实现符号定时，并且在多径信道下也具有较好的性能。

| Abstract: | To overcome the defects of conventional symbol timing synchronization algorithms based ontraining sequence for OFDM systems, a novel symbol timing algorithm for OFDM systems is proposed.The method uses the new preamble and inserts PN sequences. The defects in conventional algorithms areeliminated effectively. The result of simulateion shows that the novel algorithm achieves better timingprecision, and also has better performance than conventional methods in multipath channel. |
