| 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-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Turto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。

| Abstract: | 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. |
