"3G.Evolution.HSPA.and.LTE.for.Mobile.Broadband - Academic Press 2nd.Edition.Oct.2008" 本书是《3G演进：HSPA与LTE移动宽带》的第二版，由Erik Dahlman、Stefan Parkvall、Johan Sköld和Per Benging四位作者共同编写，由学术出版社（Academic Press，现为Elsevier出版集团的一部分）于2008年10月发布。该书深入探讨了3G技术的演进，特别是高速分组接入（HSPA）和长期演进（LTE）这两个关键的移动宽带技术。 3G演进： 3G技术，全称为第三代移动通信技术，是为了提供比2G系统更高的数据传输速率和更好的服务质量（QoS）。随着用户对数据需求的增加，3G技术通过引入WCDMA（宽频码分多址）和UMTS（通用移动通信系统）等标准，实现了语音和数据服务的融合，为移动互联网的发展奠定了基础。 HSPA（High-Speed Packet Access）： HSPA是3G技术的一个重要升级，它包括HSUPA（高速上行链路分组接入）和HSDPA（高速下行链路分组接入），显著提高了3G网络的数据传输速度。HSUPA提高了上行数据速率，使得上传数据如视频分享、云存储等应用变得更为流畅，而HSDPA则提升了下行速率，优化了用户下载体验。 LTE（Long Term Evolution）：作为3G演进的下一步，LTE被设计为一个全IP网络，旨在提供接近甚至超过100Mbps的峰值下载速度。LTE采用OFDM（正交频分复用）和MIMO（多输入多输出）等先进技术，极大地提高了频谱效率和数据传输速度，同时降低了延迟，为用户提供更高质量的移动宽带服务。本书第二版可能涵盖了以下内容： 1. LTE的系统架构：包括E-UTRAN（演进型UTRAN）和EPC（演进型核心网）的详细描述，以及它们如何支持更高的数据速率和更低的时延。 2. 无线接口技术：如OFDMA、SC-FDMA（单载波频分多址）的工作原理及其对性能的提升。 3. 小区部署和频率规划：如何有效利用频谱资源以最大化网络容量和覆盖范围。 4. MIMO技术：介绍多天线系统的增益和实现方式。 5. 调度算法和资源分配：阐述如何在多个用户间公平且高效地分配网络资源。 6. 移动性管理：如何在不同小区间平滑切换以保持连接的连续性。 7. VoLTE（Voice over LTE）：介绍如何在LTE网络中实现高质量的语音服务。 8. HSPA+增强：讨论HSPA的进一步增强版本，如DC-HSPA+（双载波HSPA+）和MIMO支持，以提高3G网络性能。 9. 网络演进策略：分析从3G向4G过渡的不同路径和考虑因素。该书对于理解3G到4G的演进历程，以及移动通信技术的核心概念和发展趋势具有重要价值，适合通信工程师、研究人员、行业从业者以及对该领域感兴趣的读者阅读。
