Furthermore, this paper exploringly studies an 802. 1 la high - speed wlan with the 54mbps data rate, and presents a sort of time synchronization and frequency offset estimation method based on the frequency domain auto - correlation of the unique preamble training sequence of 802. 11 plcp frame ; the method have the high time precision, the wide frequency estimat ion range and short convergence process ; and moreover, it can applied to other frame communication system
另外本文還對最高傳輸速率為54mbps的802 . 11a高速無線局域網系統進行了探索性研究,討論了ofdm調制技術在無線局域網中的應用;結合802 . 11a物理層數據幀結構特點,提出了一種基於前導訓練符號序列的頻域自相關時間和頻率同步方法,此方法具有定時精度高、頻偏估計范圍寬和同步建立迅速等特點,也適合於其它幀通信應用場合。 -
Provides a preamble, which is an array of bytes that you can prefix to the sequence of bytes resulting from the encoding process
