目前的智能机在硬件上多采用双cpu的架构，一个是基带处理器，主要处理数字信号、语音信号的编码解码以及GSM通信协议，另一个是应用处理器，运行操作系统和各种应用程序。基带处理器、射频和其它外围芯片作为一个模块，成为GSM/GPRS modem，提供AT命令接口。网络的应用已经是一个需求的热点，而目前的GSM模块大多都能支持GPRS功能。应用处理器通过AT命令集与带GPRS功能的无线通讯模块通信，为实现网络的应用提供了一个最底层的支持。 -Intelligent machines in the current hardware on many dual-cpu architecture of a baseband processor are mainly deal with digital signals, voice signals, and GSM codecs communication protocol, and the other is the application processor, operating system and applications running procedures. Baseband processor, radio frequency and other peripheral chips, as a module, as a GSM/GPRS modem, provided by AT command interface. Application of network needs is a hot spot, and most of the current GSM module can support GPRS function. Application processor through the AT command set and functionality with GPRS wireless communication module, in order to achieve the application of the network provides a bottom support.

接口电路代码实现下位机ATmega16通过USB口的CH372接收上位机下传的信息。上位机是利用C#实现的一个应用窗口，用于发送命令。下位机将接收到的命令发送到电力线载波模块，通过调制在电力线上传输到远方的对端。

用于产生解析信号，产生一个信号的同相和正交分量以及包络和相位-used to produce analytical signal, a signal generated in the same phase and quadrature components and the envelope and phase

这是一份介绍SIP协议的PPT，详细介绍了SIP协议，可以帮助SIP开发人员理解SIP协议各个消息中的头域，以及应用流程。-this is a point for the sip, it introduces the protocol of sip, it can help for programer for understanding the part

3GCDMA1x EVDO的资料，做通信和测试的会用到，详细介绍了EVDO的发展和空中接口、实现方式等-3GCDMA1x EVDO data, and communications and will be used to test the details of the development and EVDO air interface, such as the realization of the way

衰落信道的子程序，可结合其他衰落信道进行研究比较，适合OFDM通信-Fading subroutines can be combined with other comparative studies fading for OFDM communications

堆积（heap）是树结构的第三种型态。堆积是一棵二元树，其左右子树节点的值均较其父母节点的值小。堆积的根节点值保证是该树最大值。这中堆绩称为最大堆绩。堆积的子树可摆在左边当左子树，也可摆在右边当右子树，因此左右子树俱有相同的性质。-Heap (heap) are the third type of tree structure. Accumulation is a binary tree, its about the value of subtree nodes than those of their parents the value of small nodes. Accumulation are the root of the tree to ensure that the value of Maximum. This is known as the greatest performance in the reactor performance heap. Accumulation of sub-tree can be placed at the left when the left subtree can also be placed on the right when the right subtree, so there is about the same subtree of the nature of both.
