Scramblers and shift register generators (SRG) have been used for decades in the shaping of digital transmission signals and in generating pseudo-random binary sequences for transmission applications. In recent years more attention has been paid to this area than ever before due to the change of today's telecommunication environment. This publication presents the theory and applications of three scrambling techniques - Frame Synchronous Scrambling (FSS), Distributed Sample Scrambling (DSS) and Self Synchronous Scrambling (SSS) with an emphasis on their application in digital transmission. Based on the authors' research over the past ten years, this is the first book of its kind.
This invaluable text addresses spreading, scrambling and synchronization techniques for use in inter-cell synchronous and asynchronous CDMA systems, including the IMT-2000. It provides fundamental background material and introduces novel acquisition techniques that enable rapid and robust acquisition of inter-cell synchronous and asynchronous IMT-2000 CDMA systems.
The first book to explain the principals behind mobile 3D hardware implementation, helping readers understand advanced algorithms, produce low-cost, low-power SoCs, or become familiar with embedded systems As mobile broadcasting and entertainment applications evolve, there is increasing interest in 3D graphics within the field of mobile electronics, particularly for handheld devices. In Mobile 3D Graphics SoC, Yoo provides a comprehensive understanding of the algorithms of mobile 3D graphics and their real chip implementation methods. 3D graphics SoC (System on a Chip) architecture and its interaction with embedded system software are explained with numerous examples. Yoo divides the book into three sections: general methodology of low power SoC, design of low power 3D graphics SoC, and silicon implementation of 3D graphics SoCs and their application to mobile electronics. Full examples are presented at various levels such as system level design and circuit level optimization along with design technology. Yoo incorporates many real chip examples, including many commercial 3D graphics chips, and provides cross-comparisons of various architectures and their performance. Furthermore, while advanced 3D graphics techniques are well understood and supported by industry standards, this is less true in the emerging mobile applications and games market. This book redresses this imbalance, providing an in-depth look at the new OpenGL ES (The Standard for Embedded Accelerated 3D Graphics), and shows what these new embedded systems graphics libraries can provide for 3D graphics and games developers.
