摘要

在OFDM-MIMO系统中，为提高LS估计的性能，提出了一种附加处理方法。该新技术是基于对功率延迟分布的了解。当采用先进的MIMO自适应技术(如切换算法)时，改进估计器的应用是有用的，并导致决策准则精度的显著提高，从而导致误码率的提高。

Improvement technique of channel estimation in OFDM-MIMO systems

This paper presents an extra processing added to conventional LS estimation to improve its performances in OFDM-MIMO systems. The new technique is based on the knowledge of the power delay profile. The application of the improved estimator is useful when employing advanced MIMO adaptation techniques such switching algorithms and leads to significant improvement in decision criterion precision and consequently in terms of BER.
