谐波失真问题的数学框架。这个公式有有趣的类比，在阵列处理和多用户检测的研究问题。基于此框架，首先推导出一种最小均方误差均衡器。利用特征向量的独特结构，提出了一种非迭代的低复杂度盲均衡器。现有的谐波抑制方法进行了分析，在这个框架内。所提出的均衡器可以被证明是显着优于现有的方法中存在的大干扰。
A mathematical framework is developed for the harmonic distortion problem. This formulation has interesting analogies to well-studied problems in array processing and multiuser detection. Based on this framework, a minimum mean squared error equalizer is first derived. By exploiting the unique structure of the signature vectors, a noniterative low-complexity blind equalizer is proposed. Existing harmonic rejection approaches are analyzed within this framework. The proposed equalizer can be shown to significantly outperform existing approaches in the presence of large interferers.
