Описание: The benefits and success of multi-carrier (MC) modulation on one side and the flexibility offered by the spread spectrum (SS) technique on the other side have motivated many researchers to investigate the combination of both techniques since 1993. This combination known as multi-carrier spread spectrum (MC-SS) benefits from the advantages of both systems and offers high flexibility, high spectral efficiency, simple detection strategies, narrow-band interference rejection capability, etc. The basic principle of this combination is straightforward: The spreading is performed as direct sequence spread spectrum (DS-SS) but instead of transmitting the chips over a single carrier, several sub-carriers are employed. The MC modulation and demodulation can easily be realized in the digital domain by performing IFFT and FFT operations. The separation of the users’ signals can be performed in the code domain. MC-SS systems can perform the spreading in frequency direction, which allows for simple signal detection strategies. Since 1993, MC-SS has been deeply studied and new alternative solutions have been proposed. Meanwhile, deep system analysis and comparison with DS-CDMA have been performed that show the superiority of MC-CDMA. The aim of Multi-Carrier Spread-Spectrum is to edit the ensemble of the newest contributions and research results in this new field that have been presented during the 5th International Workshop on Multi-Carrier Spread-Spectrum (MC-SS 2005), held in Oberpfaffenhofen, Germany.

Описание: The explosive demand in wireless-capable devices, especially with the proliferation of multiple standards, indicates a great opportunity for adoption of wireless technology at a mass-market level. This title discusses circuit and system solutions for multiple communication standards and future generations of wireless communications.
Описание: There has been an increasing demand for Wireless Local Area Network (WLAN) systems in the past few years. New frequency bands are allocated and new standards are being developed to accommodate higher data rates. The fast trend of CMOS scaling has provided an opportunity for the development of low cost integrated WLAN systems. Frequency synthesizers are one of the main building blocks of wireless transceivers. The high frequency digital frequency dividers in a phase-locked loop (PLL) based frequency synthesizer are among the most challenging blocks to design and usually account for a large percentage of the synthesizer total power dissipation. The successful design and integration of a high frequency PLL demands a comprehensive understanding of wireless systems, RF circuits, and loop stability issues. Multi-GHz Frequency Synthesis & Division starts with an overview of WLAN systems and reviews the WLAN market and standards. It then studies PLLs as an essential building block of WLAN receivers, and provides guidelines and engineering recipes for the design of loop filters in high frequency PLLs. Additionally, the book investigates different analog and digital frequency division techniques and introduces injection-locked frequency dividers (ILFDs) as an alternative for conventional frequency dividers. Finally, the book demonstrates a successful design of a fully integrated CMOS frequency synthesizer for a 5 GHz WLAN receiver. Multi-GHz Frequency Synthesis & Division will be of interest to RF and high-speed analog circuit designers and students as well as wireless engineers.
