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.

IRP是信息资源规划(Information Resource Planning)的简称。信息资源规划是指对企业生产经营所需要的信息,从采集、处理、传输到使用的全面规划。以制造企业为例,不论产品设计、材料配件采购、加工制造和总装,还是销售和客户服务等等过程,无不充满着信息的产生、流通和运用。要使每个部门内部,部门之间,部门与外部单位的频繁、复杂的信息流畅通,充分发挥信息资源的作用,不进行统一的、全面的规划是不可能的。-IRP Information Resource Planning (Information Resource Planni ng), the abbreviation. Information Resources Planning refers to the production and operation of enterprises the information they need, from the collection, processing, transmission, and use of comprehensive planning. In manufacturing enterprises as an example, whether the product design, material parts procurement, processing and assembly. the sales and customer service process, fraught with all the information generated, circulation and use.

直接序列扩频通信可以有效地抵抗来自信道中的窄带干扰。在一个直扩通信系统中,扩频是通过伪噪声序列(PN)对发送的信息数据进行调制来实现的。在接收端,原伪噪声序列和所收信号的相关运算可将窄带干扰扩展到DS信号的整个频带,使干扰等效为幅度较低频谱较平坦的噪声;同时,将DS信号解扩,恢复原始信息数据。-direct sequence spread spectrum communication can be effective resistance from the channel narrowband interference. In a DSSS system. Spreading through the sequence of pseudo-noise (PN) to send the right message to data modulation to achieve. On the receiving end, the original pseudo-noise sequence and the received signal may be related Operational narrowband interference signal DS extended to the whole band, make tampering equivalent to a lesser extent than the flat spectrum of noise; Meanwhile, the DS signal disspreaded restore the original data.
