Written by an expert in the field, this book covers theprinciples, architectures, applications, specifications andcharacterizations of radio receivers
In this book, the author introduces the reader to the basicprinciples and theories of present-day communications receivertechnology. The first section of the book presents realizationconcepts at the system level, taking into consideration the varioustypes of users. Details of the circuitry are described providingthe reader with an understanding of fully digitized radioreceivers, offering an insight into the state-of-the-art.
The remaining sections address radio receivers, particularly astwo-port devices. Furthermore, the author outlines the fields ofapplications (with sample calculations and with reference topractical work) and their features and considers also the specialtyof high-quality radio receivers. As can be seen from the multitudeof terrestrial applications described in Part II, they aretypically used for radio surveillance, signal intelligence, modernradio bearing and at the classical radio services. Parts III and IVdescribe the entire range of parameters that are useful for thecharacterization of these receivers. The description starts fromthe physical effect, or the explanation of the individualparameter, and then proceeds to the measuring technique fordetermining the parameters, highlighting problems, followed byexplanatory notes with applicatory relevance. The measuringprocedures described are the result of experiences gained inextended laboratory work and practical testing. With the modelshown in Part IV, used for the operational evaluation detailing theintrinsic small range of interpretation, the book covers untreatedresearch in the field. The Appendix provides among others valuableinformation about the dimensioning of receiving systems and themathematical derivation of non-linear effects and as well as auseful method for converting different levelspecifications.
Key Features:
* Introduces the basic principles and theories of present-daytechnology
* Discusses concepts at system level (aligned to the varioustypes of users)
* Addresses (fully) digitized radio receivers focusing on thestate-of-the-art
* Close contacts to the industry were utilized to show backgroundinformation
* Enables the reader to comprehend and evaluate thecharacteristic features and the performance of such systems
* Examines the entire range of parameters that are characteristicof the technology including the physical effect and measuring techniques
* Includes results of experiences gained in extended laboratorywork and practical testing with examples
* Provides a uniform and systematic approach for ease ofunderstanding e.g. many didactic figures for the visualillustration have been newly created as well as complete real-worldexamples
This book will be an excellent resource to understand theprinciples of work, for professionals developing and testing radioreceivers, for receiver users (e.g. at regulatory agencies,surveillance centers, secret services, classical radiocommunications services), technicians, engineers and technicianswho work with RF-measurement instruments, postgraduate studentsstudying in the field and university lecturers. Chartered radioamateurs and handlers/operators will also find this bookinsightful. Due to high level of detail, it also serves as areference. By using the carefully edited alphabetical index withover 1,200 entries, the appropriate explanations can be foundquickly in the text.

Über Autor(innen)

Ralf Rudersdorfer, born in 1979, began his career at the Institute for Applied Physics. He then changed to the Institute for Communications Engineering and RF-Systems (formerly Institute for Communications and Information Engineering) of the Johannes Kepler University Linz, Austria, to take over the laboratory area and technical agendas of the Institute. His activities included the setting up of a measuring station with attenuated reflection properties / antenna measuring lab and furnishing the electronic labs of the Mechatronics Department with new basic equipment.
He began publishing technical papers at the age of 21. In August 2002 he became a Guest Consultant for laboratory equipment and RF hardware and conducted practical training courses in "Electronic Circuit Engineering" at the reactivated Institute for Electronics Engineering at the Friedrich Alexander University Erlangen-Nuremberg, Germany. In 2006 he applied for a patent covering the utilization of a specific antenna design for two widely deviating ranges of operating frequencies, which was granted within only 14 months without any prior objections. In the winter semesters 2008 to 2011 he gets the lectureship for the practical course "Applied Electrical Engineering" at the Johannes Kepler University Linz, Austria.
Rudersdorfer is author of numerous practice-oriented publications in the fields of radio transmitters and radio receivers, high-frequency technology, and general electronics. Furthermore, he was responsible for the preparation of more than 55 measuring protocols regarding the comprehensive testing of transmitting and receiving equipment of various designs and radio standards issued and published by a trade magazine. During this project alone he defined more than 550 intercept points at receivers. He has repeatedly been invited to present papers at conferences and specialized trade fairs. At the same time he is active in counseling various organizations like external cooperation partners of the university institute, public authorities, companies, associations, and editorial offices on wireless telecommunication, radio technology, antenna technology, and electronic measuring systems.
At the VHF Convention Weinheim, Germany, in 2003 he received the Young Talent Special Award in the radio technology section. At the short-wave/VHF/UHF conference conducted in 2006 at the Munich University of Applied Sciences, Germany, he took first place in the measuring technology section. The argumentation for the present work in its original version received the EEEfCOM Innovation Award 2011 as a special recognition of achievements in Electrical and Electronic Engineering for Communication.
