Available in PDF, EPUB and Kindle. Book excerpt: With the apparition of several new civilian signals in the years to come, there will soon be great demand for multifrequency receivers. As soon as two signals will be available, users will be able to correct the ionospheric error, the main source of error since the SA has been disabled. Multifrequency receivers will also be able to switch between the current L1 C/A code and the new modernized signals to make best use of their individual characteristics. As expected, the improvements in performance will be accompanied by an increase in complexity, more noticeably at the RF front-end. In this paper, we discuss the different solutions to realize an RF front-end for a dual-frequency GPS receiver and propose an innovative solution which has a power consumption comparable with that of a single-frequency front-end.

Available in PDF, EPUB and Kindle. Book excerpt: While the Global Positioning System (GPS) is best known for its positioning applications, another way to use GPS is as a time reference for telecommunication networks synchronization. However, as every new communication standard is more demanding, the precision of the current single-frequency GPS based network synchronization solutions is about not to be sufficient anymore. The dominant source of error in current state-of-the-art receivers based on the L1 C/A code is due to the variations of the propagation delay through the ionosphere. Fortunately, a new GPS civilian signal, L2CS, is about to be released. Combined with the existing L1 signal, it will allow to cancel most of the ionosphere induced error and therefore offer better timing signals as compared to classical GPS receivers. In this paper, a dual-frequency front-end for long antenna-GPS receiver links is presented.
Download or read book Navigation Signal Processing for GNSS Software Receivers written by Thomas Pany and published by Artech House. This book was released on 2010 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advancement of software radio technology has provided an opportunity for the design of performance-enhanced GNSS receivers that are more flexible and easier to develop than their FPGA or ASIC based counterparts. Filling a gap in the current literature on the subject, this highly practical resource offers you an in-depth understanding of navigation signal detection and estimation algorithms and their implementation in a software radio. This unique book focuses on high precision applications for GNSS signals and an innovative RTK receiver concept based on difference correlators. You learn how to develop navigation receivers for top performance using basic algorithms, like correlation and tracking, which can be understood on an intuitive level. Additionally, the book provides you with a theoretical framework for signal estimation and detection that gives you the knowledge you need to make performance assessments without building a receiver. The theoretical treatment also gives you hints for choosing optimal algorithms for your projects in the field.
Download or read book FPGA based Implementation of Signal Processing Systems written by Roger Woods and published by John Wiley & Sons. This book was released on 2017-05-01 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: An important working resource for engineers and researchers involved in the design, development, and implementation of signal processing systems The last decade has seen a rapid expansion of the use of field programmable gate arrays (FPGAs) for a wide range of applications beyond traditional digital signal processing (DSP) systems. Written by a team of experts working at the leading edge of FPGA research and development, this second edition of FPGA-based Implementation of Signal Processing Systems has been extensively updated and revised to reflect the latest iterations of FPGA theory, applications, and technology. Written from a system-level perspective, it features expert discussions of contemporary methods and tools used in the design, optimization and implementation of DSP systems using programmable FPGA hardware. And it provides a wealth of practical insights—along with illustrative case studies and timely real-world examples—of critical concern to engineers working in the design and development of DSP systems for radio, telecommunications, audio-visual, and security applications, as well as bioinformatics, Big Data applications, and more. Inside you will find up-to-date coverage of: FPGA solutions for Big Data Applications, especially as they apply to huge data sets The use of ARM processors in FPGAs and the transfer of FPGAs towards heterogeneous computing platforms The evolution of High Level Synthesis tools—including new sections on Xilinx's HLS Vivado tool flow and Altera's OpenCL approach Developments in Graphical Processing Units (GPUs), which are rapidly replacing more traditional DSP systems FPGA-based Implementation of Signal Processing Systems, 2nd Edition is an indispensable guide for engineers and researchers involved in the design and development of both traditional and cutting-edge data and signal processing systems. Senior-level electrical and computer engineering graduates studying signal processing or digital signal processing also will find this volume of great interest.
Download or read book The Zynq Book written by Louise H. Crockett and published by . This book was released on 2014 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the Zynq-7000 All Programmable System on Chip, the family of devices from Xilinx that combines an application-grade ARM Cortex-A9 processor with traditional FPGA logic fabric. Catering for both new and experienced readers, it covers fundamental issues in an accessible way, starting with a clear overview of the device architecture, and an introduction to the design tools and processes for developing a Zynq SoC. Later chapters progress to more advanced topics such as embedded systems development, IP block design and operating systems. Maintaining a 'real-world' perspective, the book also compares Zynq with other device alternatives, and considers end-user applications. The Zynq Book is accompanied by a set of practical tutorials hosted on a companion website. These tutorials will guide the reader through first steps with Zynq, following on to a complete, audio-based embedded systems design.
