为了降低正交频分复用OFDM(Orthogonal Frequency division Multiplexing)系统中最小均方误差MMSE(Minimum Mean Square Error)信道估计算法的复杂度,并且改善由于信道的统计特性与先验知识不匹配而导致的MMSE估计性能恶化,提出了一种自适应的低秩信道估计算法。 2. ...
The linear minimum mean-square error (LMMSE) estimation plays an important role in nonlinear estimation. Generalized LMMSE (GLMMSE) estimation is proposed in this work. LMMSE estimation finds the best estimator in the set of all estimators that are linear in the data. We extend this candidate ...
