season解答的关于在NS仿真中出现的比较棘手的问题，这些问题中的很多问题在NS仿真中都会出现，而且如果对ns理解不深入的话很难及时解决，NS高手season详细解答了这些问题，在ns仿真中会起到事半功倍的效果。-season to answer on the NS simulation appears more difficult issues in many of the problems in the NS simulation will occur, but if ns does not understand the depth resolved in a timely manner, then it is very difficult, NS masters season to answer these questions in detail, in ns simulation will play effectively.

主要是通过应用程序对skype进行进程间常用功能的控制（如呼叫，挂接电话等），并且整合了PSTN电话功能（需相应的硬件）．实现了网络电话与传统的pstn电话与一体．-Mainly through the application of the skype feature commonly used to carry out inter-process control (such as call, articulated phone, etc.), and the integration of PSTN telephony functions (subject to the appropriate hardware). Realize the network with the traditional PSTN telephone call with one.

硕士学位论文:LDPC码在瑞利衰落信道中的性能分析 信道编码技术可以带来编码增益，节省宝贵的功率资源，己经成为现代数字 通信系统中必不可少的关键技术。LDPC码采用低复杂度的迭代译码算法，且具有 逼近香农限的性能.由于LDPC码具有诸多优点，它在信息可靠传输中的良好应 用前景己经引起学术界和rr业界的高度重视，成为当今信道编码领域最受瞩目的 研究热点之一。 本文主要探讨了LDPC码在瑞利衰落信道中的性能，基于LDPC码的分组空 时码系统，以及基于LDPC码的正交频分复用系统.-master"s degree thesis : LDPC codes in Rayleigh fading channels Performance Analysis channel coding technology can bring coding gain, Power saving valuable resources have become modern digital communication systems essential to the critical technologies. LDPC low complexity of the iterative decoding algorithm, having approximation Shannon limit performance. Because LDPC has many advantages, It reliable transmission of information in the application of good prospects has been caused rr academia and industry are taking, become the channel coding areas of the most watched one of the hot spots. This paper mainly discusses the LDPC Rayleigh fading channels in the performance Based on LDPC a space-time coding system, and based on LDPC
