LS
- LS(Least Square,最小二乘法)算法是信道估计算法中最基本的算法之一。在MIMO-OFDM系统中,经常选择LS算法或其改进算法对信道进行估计。利用LS算法设计信道估计器,算法结构简单易于实现,且估计器不需要知道信道中各个收发天线对之间的自相关矩阵和噪声。-LS (further Square, Least Square) algorithm is one of the most basic algorithm of channel estimation algorithm. In M
Channel-Estimation-for-DBLAST-OFDM-Systems
- Abstract—Diagonal Bell Laboratories Layered Space-Time (DBLAST) structure offers a low complexity solution to realize the attractive capacity of Multiple-input and multiple-output (MIMO) systems. In this paper, we apply D-BLAST in orthogonal fr
