Available in PDF, EPUB and Kindle. Book excerpt: The requirements for higher computational capacity and lower cost of future high end real-time Digital Signal Processing (DSP) applications are rapidly growing. As a promising technique in wireless communication systems, Multiple-Input Multiple-Output (MIMO) enables significant high data rate wireless transmission, but on the other hand requires significant computing capacity from the underlying platform to enable real-time computing. Modern MIMO base stations use hundreds of DSP processors to enable this computing requirements, the solution however is still limited in computing capacity, and is high in power consumption, resource cost and size. In addition, high data rate services from MIMO detectors require high performance detection algorithms. Whilst significant progress has been made, the computational complexity of the algorithms is still very high. The thesis solves this problem from both embedded implementation and algorithm perspectives. In this thesis, a high performance and area efficient Field Programmable Gate Array (FPGA) based Processor Element (FPE) architecture has been presented. FPE is designed for FPGA-based DSP, enabling a powerful mix of software programmability and hardware configurability by constructing heterogeneous networks of softcore processors. To verify the performance and efficiency of FPE, a massively parallel softcore processor architecture has been constructed for Fixed-Complexity Sphere Decoder (FSD) MIMO, the resulting architecture enables real-time detection with hardware cost competitive to dedicated circuitry. It is the first software programmable architecture which supports the 480 Mbps throughput and 4 us latency of 802.11 n, with hardware cost competitive to dedicated circuit designs. I Through the exploration of hardware and software optimisation strategies of the processor, the computing capacity of FPGA can be efficiently exploited, and the resulting massively parallel softcore processor architecture for MIMO not only achieves the real-time throughput requirements of cutting edge wireless standards, but also enables 42% less equivalent hardware resources and 149\% increase in equivalent hardware efficiency compared to dedicated circuit design without redesigning the Hardware Description Language (HDL)/Register Transfer Level (RTL) hardware. This technique offers the potential to reduce the architecture design problem for DSP systems in general, and dynamic DSP design problems in particular, from a custom circuit design problem to a more tractable processor array configuration and programming problem, with no reduction in implementation efficiency or performance. In addition to high performance embedded architectures, two novel preprocessing algorithms for MIMO detection have been presented. State-of-the-art MIMO detector algorithms, such as FSD, rely on O(M_t"4) complexity of channel sequence preprocessing by Vertical-Bell Laboratories Layered Space-Time (V-BLAST). This high complexity preprocessing stage has not been recorded as real-time. By combining Sorted OR Decomposition (SORD) and Post Sorting Optimisation Algorithm (PSOA) with a particular FSD ordering scheme, this thesis describes a computationally efficient preprocessing solution for FSD. When compared to conventional MIMO preprocessing algorithms, SORD reduces the computational complexity of 4x4 to 7x7 MIMO cases by over 60-70%, suffering merely 0.16-0.26 dB performance reduction at the Bit Error Rate (BER) of 10"{-4}; in the cases where SORD fails to find optimal order, e.g., 8x8 to 16x16 MIMO cases, PSOA is applied after SORD to reduces the complexity by 28-55%, maintaining quasi Maximum Likelihood (quasi-ML) performance. The first real-time preprocessor architecture implemented by massively parallel softcore on FPGA also presents this saving.

Download or read book High level Synthesis written by Michael Fingeroff and published by Xlibris Corporation. This book was released on 2010 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: Are you an RTL or system designer that is currently using, moving, or planning to move to an HLS design environment? Finally, a comprehensive guide for designing hardware using C++ is here. Michael Fingeroff's High-Level Synthesis Blue Book presents the most effective C++ synthesis coding style for achieving high quality RTL. Master a totally new design methodology for coding increasingly complex designs! This book provides a step-by-step approach to using C++ as a hardware design language, including an introduction to the basics of HLS using concepts familiar to RTL designers. Each chapter provides easy-to-understand C++ examples, along with hardware and timing diagrams where appropriate. The book progresses from simple concepts such as sequential logic design to more complicated topics such as memory architecture and hierarchical sub-system design. Later chapters bring together many of the earlier HLS design concepts through their application in simplified design examples. These examples illustrate the fundamental principles behind C++ hardware design, which will translate to much larger designs. Although this book focuses primarily on C and C++ to present the basics of C++ synthesis, all of the concepts are equally applicable to SystemC when describing the core algorithmic part of a design. On completion of this book, readers should be well on their way to becoming experts in high-level synthesis.

The issue has become the bottleneck in the design of electronic systems, including both hardware and software, in several major industrial fields, including telecommunications, automotive and aerospace engineering. The major difficulty with the subject is that it demands contributions from several research fields, including system specification, system architecture, hardware design, and software design. Most existing book cover well only a few aspects of system-level synthesis. The present volume presents a comprehensive discussion of all the aspects of system-level synthesis. Each topic is covered by a contribution written by an international authority on the subject.
Download or read book LTE Security written by Dan Forsberg and published by John Wiley & Sons. This book was released on 2011-06-09 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing the security solutions for LTE, a cellular technology from Third Generation Partnership Project (3GPP), this book shows how LTE security substantially extends GSM and 3G security. It also encompasses the architectural aspects, known as SAE, to give a comprehensive resource on the topic. Although the security for SAE/LTE evolved from the security for GSM and 3G, due to different architectural and business requirements of fourth generation systems the SAE/LTE security architecture is substantially different from its predecessors. This book presents in detail the security mechanisms employed to meet these requirements. Whilst the industry standards inform how to implement systems, they do not provide readers with the underlying principles behind security specifications. LTE Security fills this gap by providing first hand information from 3GPP insiders who explain the rationale for design decisions. Key features: Provides a concise guide to the 3GPP/LTE Security Standardization specifications Authors are leading experts who participated in decisively shaping SAE/LTE security in the relevant standardization body, 3GPP Shows how GSM and 3G security was enhanced and extended to meet the requirements of fourth generation systems Gives the rationale behind the standards specifications enabling readers to have a broader understanding of the context of these specifications Explains why LTE security solutions are designed as they are and how theoretical security mechanisms can be put to practical use
