Blind Spectrum Sensing for Cognitive Radio Based on Model Selection

系统的介绍了瑞丽信道 和莱斯信道的特性 给出了基于MATLAB的仿真程序-Ruili introduce a system of channels and channel characteristics Rice give MATLAB-based simulation program

串口通信的源码，可以在vc6.0编译工具上编译通过，是学习串口通信的好源码。

1122和1123[Braden 1989a, 1989b]。RFC 1122针对链路层、网络层和运输层；RFC 1123针对应用层。这两个RFC对早期重要的RFC文档作了大量的纠正和解释。如果要查看有关协议更详细的细节内容，它们通常是一个入口点。它们列出了协议中关于“必须”、“应该”、“可以”、“不应该”或者“不能”等特性及其实现细节。-1122 and 1123 [Braden 1989a, 1989b]. RFC 1122 for the link layer, network layer and transport layer RFC 1123 for the application layer. The two pairs of significant early RFC documents RFC made a lot of correcting and explanation. If you want to view more details about the details of the agreement, which is usually an entry point. They are listed in the agreement on the " must," " should," " may," " should" or " can not" and other characteristics and implementation details.

自己写的用于modbusrtu的通讯，可以连接各类变频器温控仪等，而且是完整的工程文件，可以修改做他用-himself wrote for modbusrtu communications, can be connected to various types of converter temperature control instrument, but it is a complete engineering documents can be amended so he

链路路径损耗包括距离相关的路径损耗，阴影衰落，快衰落和天线增益。仿真考虑了域频 和时域快速信道变化。在每个RB中，信道（TX和RX天线之间的链路）被假定为具有零均值的复杂性白高斯随机变量，这在RB的频率范围内（180千赫）和 1 毫秒的持续时间内是恒定的。相邻的RB和时间间隔之间的信道变动是独立的。
