Paperback. Condizione: new. Paperback. 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 dissipationDescribes the implementation scenario of the most promising linearization technique, digital predistortionPresents some experimental demonstrations of digital predistortion when the device under test is in the loopBecause 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. Shipping may be from multiple locations in the US or from the UK, depending on stock availability.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Power Amplifiers (PAs) are one of the key elements in communication systems and they are nonlinear in a certain operation region. The nonlinearity generates spectral regrowth, which leads to Adjacent Channel Interference (ACI) and…violations of the out of band emission. To reduce the nonlinearity, the power amplifier can be backed off to operate within the linear portion of its operating curve. However, transmission formats such as Wideband Code Division Multiple Access (WCDMA) and Orthogonal Frequency Division Multiplexing (OFDM), have high Peak to Average Power Ratios (PAPR), it means the large fluctuations in their signal envelopes. This means that the power amplifier needs to be backed off far from its saturation point, which results in very low efficiencies, typically less than 10% , more than 90% of the dc power is lost and turns into heat. By increasing the number of the base stations and then the number of power amplifiers, improvement in efficiency of the power amplifier reduce the cost of the system. To enhance the power amplifier efficiency without compromising its linearity, power amplifier linearization is essential. 140 pp. Englisch.
