商品描述
Power Efficiency in Broadband Wireless Communications focuses on the improvement of power efficiency in wireless communication systems, especially of mobile devices. Reviewing cutting-edge techniques for conserving power and boosting power efficiency, the book examines various technologies and their impact on consumer devices. It considers each technology, first by introducing the main physical layer components in recent wireless communication systems along with their shortcomings, and then proposing solutions for overcoming these shortcomings.
The book covers orthogonal frequency division multiplexing (OFDM) signal generation and formulation and examines the advantages and disadvantages of OFDM systems compared to alternative multiplexing. It introduces one of the main drawbacks of OFDM systems, peak-to-average power ratio (PAPR), and discusses several PAPR techniques. It also explains how to overcome the main drawbacks of real-world OFDM system applications.- Considers power amplifier linearization for increasing power efficiency and reducing system costs and power dissipation
- Describes the implementation scenario of the most promising linearization technique, digital predistortion
- Presents some experimental demonstrations of digital predistortion when the device under test is in the loop
Because the most costly device in a communication system that has a direct impact on power efficiency and power consumption is the power amplifier, the book details the behavior and characteristics of different classes of power amplifiers. Describing the evolution of the mobile cellular communication system, it details a cost-effective technique to help you increase power efficiency, reduce system costs, and prolong battery life in next generation mobile devices.
商品描述(中文翻譯)
《寬頻無線通信中的功率效率》專注於改善無線通信系統中的功率效率，特別是移動設備的功率效率。該書回顧了節能和提升功率效率的尖端技術，並檢視各種技術及其對消費者設備的影響。它考慮了每種技術，首先介紹最近無線通信系統中的主要物理層組件及其缺點，然後提出克服這些缺點的解決方案。
本書涵蓋了正交頻分多工（OFDM）信號的生成和公式，並檢視了OFDM系統與其他多工技術相比的優缺點。它介紹了OFDM系統的一個主要缺點，即峰值與平均功率比（PAPR），並討論了幾種PAPR技術。它還解釋了如何克服現實世界中OFDM系統應用的主要缺點。
- 考慮功率放大器的線性化，以提高功率效率並降低系統成本和功率損耗
- 描述最有前景的線性化技術——數位預失真（digital predistortion）的實施場景
- 提供在被測試設備在迴路中的數位預失真的一些實驗示範
由於在通信系統中，對功率效率和功率消耗有直接影響的最昂貴設備是功率放大器，因此本書詳細介紹了不同類別功率放大器的行為和特性。描述了移動蜂窩通信系統的演變，並詳細介紹了一種具有成本效益的技術，幫助您提高功率效率、降低系統成本並延長下一代移動設備的電池壽命。
