Method for optimal estimation of a propagation channel based solely on pilot symbols, and corresponding estimator
Abstract:
Method for optimal estimation of a propagation channel based solely on pilot symbols. A base of natural vectors is formed using the correlation matrix of the channel observed solely at the positions of the pilot symbols. Channel representation is broken down in this base. The base vectors are extended to the data symbols, which allows optimal interpolation of channel estimation to the data symbols. Application to OFDM, TDMA and CDMA systems.
Abstract(Chinese):

仅基于导频符号对传播信道进行最优估计的方法。 使用仅在导频符号的位置处观察的信道的相关矩阵来形成自然矢量的基础。 频道表示在此基础上被分解。 基本向量被扩展到数据符号，这允许对数据符号的信道估计的最佳内插。 应用于OFDM，TDMA和CDMA系统。
