摘要
文中在分析OFDM无线信道模型的基础上,介绍了OFDM的同步技术,主要包括符号同步、载波同步和采样率同步。同时对这些同步技术的算法进行了分析比较,指出各自的优缺点,这对今后OFDM技术的应用和研究,具有一定的借鉴意义。
In the light of the analysis on the wireless channel model, this paper introduces OFDM synchronization technology, mainly including symbol synchronization, frequency and sample rate synchronization. At the same time, these synchronization algorithms are analyzed and compared, and their advantages and disadvantages pointed out. It may be of reference value for the further application and resesrch of the OFDM technology.
