Available in PDF, EPUB and Kindle. Book excerpt: The report covers effort expended on a theoretical and experimental investigation of methods of improving the conversion efficiency of relatively broadband linear-beam amplifiers operating at approximately 1 Mw of peak power. A design was achieved using a 'short-stack' intense- approximately 1 Mw of peak power. A design was achieved using a 'short-stack' intense-interaction cloverleaf structure; a forward-fundamental, coupled-cavity circuit. Computer-aided calculations predicted 40% minimum efficiency over a 9% bandwidth with a midband efficiency greater than 60%.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
