Description: 通信技术发展要求蜂窝运营商必须能够支持新的3G技术，在一个充满竞争的市场机制下以合理的价格提供基于多媒体业务的无线Internet能力，本书以此为蓝图主要从3部分进行阐述：
·集中阐述了GSM系统如何完全无缝演化为支持UMTS业务的GERAN。部分内容还包括演化过程中涉及的功能、结构组成、系统统一以及3G网络提出的各种UMTS QoS要求等。
·从仿真和实际系统测试的角度阐述各种先进技术的性能。本部分全面讨论了GSM、GPRS、EDGE、AMR和支持3G业务的GERAN等系统工技术的特征和性能。同时也介绍了无线接入网络的自动规划、优化和运营方法和技术。阐述了跳频技术的自动规划和无线资源管理各参数的优化等，另外对系统出现故障或者崩溃的各种原因进行了分析。
·讨论了各种不同的3G无线技术，同时说明了GERAN在这些技术中所处的地位。分析了各种演化策略，描绘了3G多无线接入网络的场景，阐述了内在的GSM和WCDMA系统无缝融合技术。 -Communication technology requirements of the development of cellular operators must be able to support the new 3G technology, in a competitive market mechanism to provide a reasonable price of wireless multimedia services based on Internet capabilities, this book as a blueprint for the major part of from 3:
Focused on how the system completely seamless GSM Evolution UMTS business to support GERAN. Part of the contents of the course also includes the evolution of function, structure, systems, and unification of the various 3G networks UMTS QoS requirements.
Simulation and from the perspective of the actual system testing on the performance of various advanced technologies. A comprehensive discussion of this part of the GSM, GPRS, EDGE, AMR and support for 3G systems such as GERAN business techniques and performance characteristics. At the same time, also introduced an automatic wireless access network planning, optimization and operation of methods and techniques. On the automatic fre

Description: GSM/gps通信程序：双串口控制。当时我编这程序时还是花了不少力气的。
(1)gsm部分：以AT指令控制西门子TC35模块。程序代码精简。也可以用于TC35i，MC45,TC45的控制.
(2)采用GPS标准协议格式，获取GPS模块发来的时间、位置、速度等信息。该程序经过试验验证.
程序中，实现GPS信息的接收，并和其它信息一起编码成GSM传输协议格式发送出去。-GSM/gps Communication Program: Two serial control. When I compile this program, or spent a lot of effort for. (1) gsm Part: AT command to control the Siemens TC35 module. Streamlined code. Can also be used TC35i, MC45, TC45 control. (2) The standard protocol format, GPS, GPS module made to obtain the time, location, speed and other information. After the test verification process. Program to achieve GPS information received, and other information with the coded format of GSM protocol to send out.

Description: The low level speech compression algorithm of the GSM suite is called GSM 06.10 RPE LTP (Regular Pulse Excitation Long Term Predictor). My colleague Dr. Carsten Bormann and I have implemented a GSM 06.10 RPE LTP coder and decoder in C. Its source code is freely available, and we encourage you to use it, play with it, and invent new real time media protocols and algorithms.
Our implementation consists of a C library and a stand alone program. Both are destined to be compiled and used on a Unix like environment with at least 32 bit integers, but others have ported it to VMS and a MS DOS 16 bit environment. GSM 06.10 is faster than code book lookup algorithms such as CELP, but by no means cheap to use it for real time communication, you will need at least a medium scale workstation. -The low level speech compression algorithm of the GSM suite is called GSM 06.10 RPE LTP (Regular Pulse Excitation Long Term Predictor).
