应用背景我们提出了分散认知的协议允许二级用户自主搜索频谱没有中央协调员或专门的机会通信信道。硬件和能量约束，我们假设一个二级用户可能无法执行全频谱感知或可能不愿意监控没有数据传输时的频谱。我们发展基于机会频谱接入的分析框架部分可观测马尔可夫决策理论的研究（POMDP）。这一决策理论方法集成了设计频谱接入协议的频谱接入协议确定的物理层和交通统计由原网络应用层。它也允许频谱感知误差和约束容易合并与主要用户的碰撞概率。在此POMDP框架，我们提出了认知MAC协议优化二次用户的性能，同时限制主用户的干扰。次优策略与减少的复杂性，但可比性能的发展。无需附加控制信息交换次级发射机和接收机，建议分散协议确保在频谱之间的同步跳频在碰撞和碰撞的存在下，发射器和接收器频谱感知误差。关键技术本文提出了一种分散的方法Ad hoc网络MAC OSA。一种新的特征这项工作是剥削的机会，在插槽水平，允许低利率应用（如传感器节点）与主要用户。POMDP框架使一个机会用户使最优基于信念向量的感知和访问决策总结了基于网络状态的知识对所有过去的决定和意见

应用背景This document describes how to set up a 6x6 multiple input, multiple output (MIMO) system using NI LabVIEW software and NI USRP™ (Universal Software Radio Peripheral) hardware. After a brief discussion of MIMO, the paper examines the hardware and software based on LabVIEW for a 6x6 MIMO-OFDM system using 4-QAM as modulation scheme. The system presented here is also capable of working as a 2x2 MIMO and 4x4 MIMO system with appropriate parameter configuration.关键技术With MIMO, you can increase wireless system performance without increasing power consumption. It is based on the idea that when using multiple antennas, the transmitted signal progresses through different wireless channels, from the transmitter antennas to the receive antennas, to
