中文说明：
一种新的符号定时和载波频率同步算法,该算法将OFDM符号分成几部分。它使用相关性和积累在几个OFDM同步算法对OFDM系统基于试点,使用前言快速、准确获取信号,在有限的时间建立同步,利用导频跟踪同步信息。
English Description：
A new symbol timing and carrier frequency synchronization algorithm divides OFDM symbols into several parts. It uses correlation and accumulation in several OFDM synchronization algorithms based on the pilot for OFDM system, uses foreword to acquire signal quickly and accurately, establishes synchronization in limited time, and uses pilot to track synchronization information.
