我们基于Jake模型重新推导了新的自相关函数，并基于新的自相关函数提出了一种通用最小均方误差（MMSE）信道估计器。 因此，由于其固有的鲁棒性，所提出的MMSE信道估计器可以被用于各种信道场景。 MMSE信道估计器的性能是通过实践DVB-T标准进行研究的，该标准表明MMSE信道估计器能以低复杂度实现非凡的最小平方误差性能(Based on the Jake model, we derive the new autocorrelation function and propose a universal minimum mean square error (MMSE) channel estimator based on the new autocorrelation function. Therefore, due to its inherent robustness, the proposed MMSE channel estimator can be used for various channel scenarios. The performance of MMSE channel estimator is studied through the practice of DVB-T standard, which indicates that MMSE channel estimator can achieve the least squared error performance with low complexity.)
