Finally, based on the DCT transform domain channel estimation, the original SVD-LMMSE algorithm has been improved. Theoretical analysis and simulation results show that: The improved SVD-LMMSE algorithm not only can reduce the complexity of the implementation, but also has more superior performance....
1) SVD-LMMSE 基于奇异值分解的线性最小均方误差估计2) LMMSE 线性最小均方误差估计 1. These serials were predicted by LMMSE and AR models respectively according to their different features. 根据低频序列和高频序列的不同特性,分别采用自回归模型(AR)和线性最小均方误差估计(LMMSE)对未来网络流量进行预测...
信道估计是LTE系统接收端至关重要的模块.本文针对采用梳状导频的下行物理信道,提出了一种基于奇异值分解的LMMSE算法,与传统的LMMSE算法相比,该算法有两个方面的改进:一是改进了信道自相关矩阵的计算方法,直接根据信道模型得到信道自相关矩阵并预先存储,在硬件实现起来更方便;二是改进了SVD分解的算法,将信道自相关矩阵分...
