摘　　要：针对符号间干扰信道,从接收信号序列服从联合高斯分布的假设出发,使用增扩的实矩阵表达推导出了一种新颖的均衡器一联合高斯均衡器,并给出了低复杂度的计算方法。使用这种低复杂度均衡器和新反馈策略的Turbo均衡系统与传统的基于最小均方误差均衡器的Turbo均衡系统相比不仅性能上有显著提高,而且复杂度大大降低。Based on the assumption that the received signal sequence over inter-symbol-interference channel is jointly Gaussian, a novel equalizer, Jointly Gassian equalizer, represented by the augmented real number matrices is developed in this paper. We also present a low-complex algorithm of this equalizer and its application on Turbo equalization. The Turbo equalization system based on Jointly Gaussian equalizer and a new feedback strategy has large gain in performance and great reduction in complexity compared with the conventional Turbo equalization system based on minimum mean squared error equalizer.
