摘 : 通过使用 peer-to-peer(P2P)计算模式在 Internet 物理拓扑基础上建立一个称为 P2P 覆盖网络(P overlay network)的虚拟拓扑结构,有效地建立起一个基于 Internet 的完全分布式自组织网络路由模型 集中式自组织网络路由模型(hierarchical aggregation self-organizing network,简称 HASN).分别描述了 HASN 由模型的构建目标和体系结构,并详细分析了 HASN 采用的基于 P2P 计算模式的分布式命名 路由发现和更 算法 HASN_Scale,并在仿真实验的基础上,对 HASN 路由模型的性能进行了验证. -pick : through the use of peer-to-peer (P2P) computing model in the physical topology based on Internet established as a peer-to-peer network coverage (P overlay network) virtual topology, to establish an Internet-based Distributed completely self-organizing network routing model of a centralized self-organizing network Tongxinluo routing model (hierarchical aggregation self-Organization The driver, network, short HASN). HASN were described by the model of the goals and structure. and HASN detailed analysis of the peer-to-peer computing model based on distributed naming and routing algorithm found HASN _Scale and simulation on the basis of HASN routing model the performance

该代码介绍了SOCKET通信的基本原理，利用C++实现了基本的组播，广播和单播通信，对理解SOCK通信有一定的帮助。

在GSM通信系统中，Viterbi检测是一个及其重要的部分，许多的研究人员在这里花费了大量的心血。参考各种资料，我们总结得出以下Viterbi软输出算法，与传统的硬判决方法相比，可以提高2～3个db的增益：-In GSM communication systems, Viterbi detection is an important part of many researchers here spent a lot of effort. Reference to a variety of information, we summarize the following soft-output Viterbi algorithm, with the traditional hard-decision method, can be raised by 2 ~ 3 db gain:
