一种适用于高数据速率和高速移动环境的新型信道估计方法——双正交通道信道估计方法

本文给出了一种适用于高数据速率和高速移动环境下的新型有效的信道估计方法-双正交通道信道估计方法(CETOC,Channel Estimation by using Two Orthogonal Channels),这种信道估计方法通过采用两个独立通道的联合估计,可以有效的克服快衰落的影响,从而使得在快衰落信道下应用多维状态调制成为可能.

Novel Channel Estimation Method Applied to High Data Rateand High Speed Mobile Communications——Channel Estimation

Channel estimation is a key technique in the field of mobile communications.Especially,with the demand of next generation mobile communications,the channel estimation theory in the high data rate and high speed mobile environment will become a dominant technique in mobile communications.This paper presents a novel method named Channel Estimation by using Two Orthogonal Channels (CETOC) method applied to high data rate and high speed mobile communications.This method can effectively overcome influence resulted from fast fading by using the joint estimation of two independent orthogonal channels,so it is possible to use high dimensional modulation in fast fading channel.
