GPRS(General Packet Radio Service)是通用分组无线业务的简称。GPRS是GSM Phase2.1规范实现的内容之一，能提供比现有GSM网9.6kbit/s更高的数据率。GPRS采用与GSM 相同的频段、频带宽度、突发结构、无线调制标准、跳频规则以及相同的TDMA帧结构。因此，在GSM系统的基础上构建GPRS系统时，GSM系统中的绝大部分部件都不需要作硬件改动，只需作软件升级。-GPRS (General Packet Radio Service) is a General Packet Radio Service abbreviation. GPRS GSM Phase2.1 norms to achieve one of the elements that can provide more than the existing GSM network 9.6kbit/s higher data rate. GSM and GPRS using the same frequency and bandwidth, unexpected structure, the wireless standard modulation, frequency hopping and the same rules TDMA frame structure. Therefore, in the GSM system builds on the GPRS system, the GSM system of most components do not need to make hardware changes, only for software upgrades.

Linux的发行版中包含了很多软件开发工具. 它们中的很多是用于 C 和 C++应用程序开发的. 本文介绍了在 Linux 下能用于 C 应用程序开发和调试的工具. 本文的主旨是介绍如何在 Linux 下使用 C 编译器和其他 C 编程工具, 而非 C 语言编程的教程. -Linux distributions contain a lot of software development tools. Many of them for C and C++ application development. In this paper, can be used in C under Linux application development and debugging tools. The main thrust of this paper is to introduce the Linux how to use C compiler and other C programming tools, rather than the C programming language tutorial.

本文提出一种基于DSP 的SPWM 波形生成新方法―单元脉冲舍入法。产生的SPWM 波经过滤波后转变成的正弦波,具有 频率高、频率范围宽、波形畸变小的特点,可以用做数据通讯的载波,并且已经成功地应用在基于DSP 的软件调制解调器中。-This paper presents a DSP-based SPWM waveform to generate new methods- unit pulse rounding method. SPWM wave generated after filtering through into the sine wave, with high frequency, wide frequency range, waveform distortion of small features, can be used to do data communications carrier and has been successfully used in DSP-based software modems.
