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.)

LTE最新物理层协议 211，212，213，214-v860(Latest LTE physical layer protocol 211,212,213,214-v860)

The following Matlab project contains the source code and Matlab examples used for speed control of a dc motor. The goal of this assignment was to develop a Speed control system for a DC motor.

CVPARTITION Create a cross-validation partition for data. An object of the CVPARTITION class defines a random partition on a set of data of a specified size. This partition can be used to define test and training sets for validating a statistical model using cross-validation.
