OFDM系统信道估计的研究

The Research on Channel Estimation in OFDM System

OFDM(正交频分复用)系统以其抗多径衰落和较高的频带利用率,得到了众多领域的广泛应用。本文就OFDM系统中关键技术之一的信道估计技术进行了介绍。并分别叙述了OFDM系统和信道估计的意义,归纳了信道估计的分类,最后介绍了各种信道估计算法。

OFDM(Orthogonal Frequency Division Multiplexing)system,because of anti-multipath fading and the higher frequency band utilization ratio,has been widely used in many fields.The thesis describes channel estimation technology,which is one of the key technolo-gies of OFDM system,then introduces OFDM system and the significance of channel estimation.The article sums up the classification of channel estimation,and introduces a variety of channel estimation algorithm.
