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: ITU-T G.722.2
国际电信联盟G.722.2建议书，2003年7月版。该建议书是语音通讯领域的压缩标准，被GSM，WCDMA，3GPP等采用，题目为16kbit下的宽带语音编码，使用自适应多率宽带编码。
内容主要有代数码激励线性预测编码(ACELP)，话音活动检测(VAD)等。-This Recommendation describes the high quality Adaptive Multi-Rate Wideband (AMR-WB)
encoder and decoder that is primarily intended for 7 kHz bandwidth speech signals. AMR-WB
operates at a multitude of bit rates ranging from 6.6 kbit/s to 23.85 kbit/s. The bit rate may be
changed at any 20-ms frame boundary.
Annex C includes an integrated C source code software package which contains the implementation
of the G.722.2 encoder and decoder and its Annexes A and B and Appendix I. A set of digital test
vectors for developers is provided in Annex D. These test vectors are a verification tool providing an
indication of success in implementing this codec.
G.722.2 AMR-WB is the same codec as the 3GPP AMR-WB. The corresponding 3GPP
specifications are TS 26.190 for the speech codec and TS 26.194 for the Voice Activity Detector.
