摘要

本文研究了在不连续块衰落信道中使用叠加导频的短ML信道估计器的MSE性能。我们所看到的早期分析MSE估计与理想反馈或不连续块方向传输无关。此外，我们对使用比真实信道长度更短的信道估计器的场景很感兴趣。在本文中，我们提出了这些建模问题的解决方案，并得到了改进的分析MSE估计。

Improved performance analysis for superimposed pilot based short channel estimator

In this paper we study the MSE performance of a short ML channel estimator in a discontinuous block fading channel using superimposed pilots. The earlier analytical MSE estimates that we have seen were not concerned with ideal feedback or discontinuous block-wise transmission. In addition, we are interested in the scenario where we use shorter channel estimator than the true channel length. In this paper, we present solutions for these modeling problems and obtain improved analytic MSE estimates.
