摘要

本文研究了一种基于叠加训练的单载波迭代消干扰接收结构。我们利用完备的信道知识推导了LMMSE信道估计器的解析MSE极限，并证明了模拟值与解析值符合得很好。然后，我们利用这些结果来分析组合ML- lmmse通道估计器结构的MSE性能，其中初始信道估计是从ML通道估计器获得的

Improved performance bounds for iterative IC LMMSE channel estimator with SI pilots

In this paper an iterative, interference cancelling receive structure for single carrier transmission using superimposed training is studied. We derive the analytical MSE limits for LMMSE channel estimator using perfect channel knowledge and show that the simulated values follow well the analytical ones. Then, we utilise these results to analyse the MSE performance of a combined ML-LMMSE chanel estimator structure, where the initial channel estimates are obtained from the ML channel estimator
