现有数字信号自动调制识别方法大多只适用于无记忆信号,如PSK、ASK、FSK信号等。将有记忆
信号(MSK信号)和无记忆信号一起考虑,提出了一种改进的数字信号自动识别方法。该方法采用信号的瞬时统
计量作为特征参数,采用多层神经网络作为分类器。计算机仿真表明:当噪声采用高斯白噪声,并且信噪比大于
l5 dB时,识别率高于96% ;当信噪比不低于l0 dB时,识别率不低于90%。-Existing digital signal automatic modulation recognition methods are mostly applied only to memoryless signals, such as PSK, ASK, FSK signals. Will have a memory signal (MSK signal) and non-memory signal into consideration, an improved digital signal automatic identification method. This method is the use of the instantaneous signal statistics as a characteristic parameter, the use of multi-layer neural network as classifier. Computer simulation shows that: When the noise using Gaussian white noise, and signal to noise ratio greater than l5 dB, the recognition rate is higher than 96 when the signal to noise ratio not less than l0 dB, the recognition rate of not less than 90.

本书全面讲解IPv6及相关协议实现的事实标准KAME,揭示了KAME IPv6协议栈的所有细节,对每行代码到底做了什么以及为什么要这样设计都进行了解释。全书共分7章,分别介绍IPv6地址结构、IPv6、ICMPv6、邻居发现和无状态地址自动配置、传输层协议及套接字API扩展。每章都包含两个主要部分:第一部分提供了作为RFC发布的主要协议规范的摘要,定义各种协议分组,解释每个分组中每个字段的含义和目的;第二部分则描述实现这些RFC的KAME的数据结构及功能。书的最后还提供了一些例子,说明如何编写既可以在IPv4网络上运行、又可以在IPv6网络上运行的可移植应用程序。.
本书是IPv6的权威参考书,适合网络设计和开发人员阅读。此外,本书还适合作为高校相关专业网络课程的教学参考书。-This book fully explain the IPv6 and related protocols, the de facto standard KAME, reveals the KAME IPv6 protocol stack all the details on each and every line of code in the end did what and why to be so designed to have carried out an explanation. The book is divided into seven chapters, describing the structure of IPv6 addresses, IPv6, ICMPv6, neighbor discovery and stateless address autoconfiguration, Transport Layer and the socket API extensions. Each chapter contains two main parts: the first part provides as RFC published a summary of the main protocol specification, defining a variety of protocols grouped in each group to explain the me
