"4G LTE LTE-Advanced for Mobile Broadband" 是一本由Erik Dahlman, Stefan Parkvall和Johan Sköld合著的专业书籍,深入解析了4G移动通信技术,特别是LTE(长期演进)和LTE-Advanced的相关内容。这本书涵盖了OFDM(正交频分复用)、SC-FDMA(单载波频分多址)以及MIMO(多输入多输出)等关键无线通信技术。 4G是第四代移动通信技术,它在3G的基础上实现了显著的性能提升,尤其是在数据传输速度、网络容量和延迟方面。LTE是4G的一个重要组成部分,其设计目标是为了提供更高的数据速率,改善用户体验,并降低运营成本。而LTE-Advanced作为4G的增强版本,进一步提升了这些性能指标,以满足未来移动宽带服务的需求。 OFDM是4G系统中最核心的技术之一,它通过将宽带信号分割成多个窄带子载波进行传输,有效地对抗了多径衰落,提高了频谱效率。SC-FDMA则是一种低功耗的上行链路传输技术,它降低了发射端的峰均功率比,从而减轻了对电池寿命的影响,尤其适合用户设备。 MIMO是4G通信中的另一项关键技术,它利用多个天线发送和接收数据,通过空间分集和空间多工来增强信号质量和提高数据吞吐量。MIMO技术不仅能提高无线通信的可靠性,还能在不增加频谱资源的情况下增加系统容量。 本书详细介绍了4G网络的架构,包括网络层次结构、信道编码、调度算法以及无线资源管理等方面,同时探讨了LTE-Advanced引入的新特性,如载波聚合、中继节点和多点协作等,这些都是为了实现更高的数据速率和更广泛的覆盖范围。 此外,书中可能还讨论了与频谱效率、服务质量保障、移动性管理、网络安全以及与其他通信技术(如Wi-Fi和5G)的互操作性相关的问题。对于想要深入了解4G技术和未来移动通信发展的读者来说,这是一本不可多得的参考书。 "4G LTE LTE-Advanced for Mobile Broadband" 提供了全面且深入的4G技术解析,对于通信行业的工程师、研究人员以及相关专业学生来说,是一本非常有价值的教材和参考资料。

这本4G LTE/LTE-Advanced for Mobile Broadband是11年出版的,写书的是Ericsson的,就是写3G Evolution: HSPA and LTE for Mobile Broadband那几个人。本书最大的特点是本书涵盖了Rel-10的最新进展内容,考虑到Rel-10刚刚结束,对标准化感兴趣或者刚入手标准化的同学可能很有帮助,强烈推荐一下。 Based on the bestseller "3G Evolution - HSPA and LTE for mobile broadband" and reflecting the ongoing success of LTE throughout the world, this book focuses on LTE with full updates including LTE-Advanced to provide a complete picture of the LTE system. Overview and detailed explanations are given for the latest LTE standards for radio interface architecture, the physical layer, access procedures, broadcast, relaying, spectrum and RF characteristics, and system performance. Key technologies presented include multi-carrier transmission, advanced single-carrier transmission, advanced receivers, OFDM, MIMO and adaptive antenna solutions, advanced radio resource management and protocols, and different radio network architectures. Their role and use in the context of mobile broadband access in general is explained. Both a high-level overview and more detailed step-by-step explanations of the LTE/LTE-Advanced implementation are given. An overview of other related systems such as GSM/EDGE, HSPA, CDMA2000, and WIMAX is also provided. This book is a 'must-have' resource for engineers and other professionals in the telecommunications industry, working with cellular or wireless broadband technologies, giving an understanding of how to utilize the new technology in order to stay ahead of the competition. The authors of the book all work at Ericsson Research and have been deeply involved in 3G and 4G development and standardisation since the early days of 3G research. They are leading experts in the field and are today still actively contributing to the standardisation of LTE within 3GPP.
