中文摘要: 本课题是无线通信信息理论和智能信息处理技术的交叉研究课题。目的是应用智能信息处理的相关特性来解决无线通信中的信号处理问题,探索智能信息处理的的优化问题,研究MIMO无线通信系统的可靠性和有效性。本课题的研究内容是基于证据理论的MIMO系统的信号检测和信息译码技术,本课题从新的视角出发,将MIMO信号判别看成是一个不确定性的推理过程,应用证据理论对不确定性的描述,定义了广义软信息的概念,并使用软信息,建立判决规则的模型,克服传统的贝叶斯理论对不确定性知识刻画不足的局限性,在证据理论的框架中研究MIMO系统的信号检测和信息译码的新方法,从不同的角度入手,探讨MIMO系统中信号检测的优化问题。

英文摘要: The project is interdisciplinary research that combines the wireless communication theory with intelligent information processing theory. The aim is to apply the intelligent theory to solve the problem of signal detection, to explore the optimization problem and to investigate the validity and reliability in wireless MIMO communication system. Based on the evidence theory, the signal detection and information processing are investigated in MIMO wireless system. From different point of view, the signal detection is considered as the reasoning processing with uncertainty. Using the soft information to describe the uncertainty, the reasoning model is established to detect the MIMO signal, which overcomes the limitation of classical Bayes theory. The new method to detect the MIMO signal is developed in the frame of evidence theory.
