Abstract

The analysis of adaptive decision feedback turbo equalization is provided. The turbo detector is a reduced-complexity adaptive turbo equalizer where trellis-based channel equalization is replaced by the adaptive decision feedback equalizer (DFE). We show that for severe intersymbol interference (ISI) the turbo effect (waterfall region) starts at lower SNR relative to the detector applying conventional MMSE DFE coefficients assuming perfect feedback.

自适应决策反馈涡轮均衡和多用户检测

对自适应决策反馈turbo均衡进行了分析。turbo检测器是一种降低复杂度的自适应turbo均衡器，其中基于栅格的通道均衡被自适应决策反馈均衡器(DFE)所取代。我们表明，对于严重的码间干扰(ISI)，涡轮效应(瀑布区)开始于较低的信噪比，相对于检测器应用传统的MMSE DFE系数假设完美反馈。
