| 摘 要： | OFDM（正交频分复用）作为一种高效可靠的传输方式，被广泛应用于无线通信系统中，近年来越来越受到人们的关注。文中主要研究基于导频的OFDM信道估计，在此基础上提出了一种采用最小二乘法的联合信道估计方法。这种方法能够将传送数据与导频结合起来进行更精确的信道估计，从而提高系统性能。仿真结果表明，文中方法优于经典的信道估计方法。

| Abstract: | Orthogonal frequency division multiplexing(OFDM),as a kind of efficient and reliable transimission technique,is widely used in wireless communication systems,and has attracted more and more attention in recent years.This paper studies the pilot-based channel estimation in OFDM systems,and proposes a least square(LS) method of joint channel estimation.This method estimates the channel information more accurate by combining the transmitted data with the pilot.So the new method improves the system performance.... |
