所谓短信猫，其实是一种工业级级GSM MODEM，通过串口与计算机连接，可以通过AT 指令控制进行短信收发的设备。国内目前应用较多的短信猫，都是以SIEMENS 或WAVECOM 模块为核心组装而成的，与普通手机相比更为稳定高效。-The so-called SMS cat is a kind of industrial-level GSM MODEM, connected through the serial port and the computer can be carried out through the AT commands to control the device to send and receive text messages. At present the application of the domestic cat more messages are to WAVECOM module SIEMENS or assembled at the core, and more stable compared to the ordinary high-performance mobile phones.

摘要:基于通信技术的列车运行控制系统(CBTC)是铁路信号的发展方向，交频分复用
OFDM)是一种无线环境下的高速传输技术，它对高速列车控制信息传输中卞要受到的由于多
径传播引起的快衰落所产生的影响有很强的抵抗能力.本文首先介绍了OFDM技术的发展和
基本原理，然后在计算机上用M atlal〕对其性能进行了仿真，仿真中将OFDM与传统的单载波
调制方式―i1，交振幅调制( 1frQAM)对抗多径十扰的性能进行了比较，最后分析了一者的仿真结果.
-Abstract: Based on the communication technology train operation control system (CBTC) is a railway signal direction for the development of cross-frequency division multiplexing OFDM) is a wireless environment of high-speed transmission technology, its high-speed train control information transmission Bian be subject to the Due to the spread of multi-path fast fading caused by the impact of a strong resistance to diseases. This paper first introduces the OFDM technology development and the basic principles, and then on the computer〕 M atlal use its performance simulation will OFDM with the traditional single-carrier modulation-i1, cross-amplitude modulation (1frQAM) against multi-path interference of the 10 properties were compared with a final analysis of

程序员对代码所做的为了满足短期利益代码改动，或再没有完全清楚增个架构下的改动，都很容易是代码失去它的清晰结构，偏离需求或设计。而这些改动的积累很容易使代码偏离它原先设计的初衷而变得不可立即和无法维护。
Refactoring则帮助重新组织代码，重新清晰的体现结构和进一步改进设计。
-programmers to code done in order to meet short-term interest code changes or not entirely clear by a framework of the changes, it is easy to lose its code is a clear structure, depart from the demand or design. And the accumulation of these changes are easier to make code from its original intention of the original design has become an immediate and unable to preserve. Refactoring is helping to reorganize code, re- clearly reflected structure and further improve the design.
