认知无线电是一种用于提高无线电通信频谱利用率的新的智能技术. 首先简述认知无线电的背景和概念,针 对认知无线电的频谱感知功能,详细地分析基于能量检测的频谱检测方法,在此基础上研究了噪声方差的不确定 性对检测性能的影响. 针对无线信号检测具有本地局域性和能量检测存在信噪比极限的特点,提出一种分布式有 限合作检测机制,推导出基于“OR”规则的有限合作机制的检测概率,并进行Monte Carlo仿真.(Cognitive radio is a radio communications spectrum used to improve the efficiency of the new smart technology. First, the background and outlined the concept of cognitive radio, spectrum sensing for cognitive radio capabilities, a detailed analysis of the spectrum based on energy detection test In this study the noise variance based on the uncertainty of the detection performance. for wireless signal detection with local detection of localized and there is signal to noise ratio limit of the energy characteristics of a distributed cooperative detection mechanism, derived out based on " OR" rules of the detection probability of the limited cooperation mechanism and conduct Monte Carlo simulation.)

这是一篇有关故障录波仪如何开发的硕士论文，论文行文清楚、逻辑分明，重点讲述了故障录波器的算法，值得看。(This is a fault recorder on how to develop the master's thesis papers lines clearly and logically distinct, and highlight the fault recorder algorithm worth observing.)

本文对16QAM解调软信息输出(LLR)理论计算方法进行分析，推导 出其简化解调算法。将两者在性能和计算复杂度方面进行了分析比较，并分别在 高斯白噪声信道和瑞利衰落信道环境下进行仿真(In this paper, 16QAM demodulator soft information output (LLR) theoretical calculation method for the analysis derived simplified demodulation algorithm. Both in performance and computational complexity aspects are analyzed and compared, and in white Gaussian noise channel and Rayleigh fading channel simulation environment)
