"This practical resource offers a thorough examination of RF transceiver design for MIMO communications. Offering a practical view on MIMO wireless systems, this book extends fundamental concepts on classic wireless transceiver design techniques to MIMO transceivers. This in-depth volume describes many theoretical and implementation challenges on MIMO transceivers and provides the practical solutions for these issues. This comprehensive book provides thorough descriptions of MIMO theoretical concepts, MIMO single carrier and OFDM modulation, RF transceiver design concepts, power amplifier, MIMO transmitter design techniques and their RF impairments, MIMO receiver design methods, RF impairments study including nonlinearity, DC-offset, I/Q imbalance and phase noise and their compensation in OFDM and MIMO techniques.

"This book consists of the identification, characterization, and modeling of electromagnetic interferences in substations for the deployment of wireless sensor networks. The authors present in chapter 3 the measurement setup to record sequences of impulsive noise samples in the ISM band of interest. The setup can measure substation impulsive noise, in wide band, with enough samples per time window and enough precision to allow a statistical study of the noise. During the measurement campaign, the authors recorded around 120 noise sequences in different substations and for four ranges of equipment voltage, which are 25 kV, 230 kV, 315 kV and 735 kV. A characterization process is proposed, by which physical characteristics of partial discharge can be measured in terms of first- and second-order statistics. From the measurement campaign, the authors infer the characteristics of substation impulsive noise as a function of the substation equipment voltage, and can provide representative parameters for the four voltage ranges and for several existing impulsive noise models."

"Detailed tutorials are included on all major topics required to understand fundamental principles behind both the main sub-circuits required to design an RF transceiver and the whole communication system. Starting with review of fundamental principles in electromagnetic (EM) transmission and signal propagation, through detailed practical analysis of RF amplifier, mixer, modulator, demodulator, and oscillator circuit topologies, all the way to the system communication theory behind the RF transceiver operation."

"Sistem pelacak bus kampus merupakan sebuah kesatuan dari perangkat-perangkat lunak maupun keras tertentu yang dapat melacak posisi dari bus kampus dan menampilkannya agar dapat dilihat oleh pengguna. Skripsi ini akan membahas sistem pelacak bus kampus di Universitas Indonesia secara keseluruhan mulai dari landasan teori tentang teknologi yang digunakan, perancangan sistem, dan hasil pengujian serta analisa sistem. Selain itu juga diadakan kuisioner yang memberikan gambaran mengenai tanggapan pengguna terhadap sistem pelacak bus kampus Universitas Indonesia ini. Perangkat lunak yang digunakan adalah cygwin sebagai compiler bahasa C. Sedangkan perangkat-perangkat keras utama yang digunakan adalah komputer, modul DT-51 LCMS 2.0 dan modul wireless YS 1020 RF Data Transceiver.
Modul DT-51 LCMS memberikan ID kepada bus berupa 8 bit biner. Oleh modul wireless YS 1020 RF Data Transceiver di sisi pengirim diteruskan dan diterima oleh modul wireless YS 1020 RF Data Transceiver di sisi penerima. Modul wireless YS 1020 RF Data Transceiver penerima yang terpasang pada komputer yang diasumsikan ada di setiap halte meneruskannya ke komputer halte tersebut agar dapat diolah dengan menambahkan ID halte dan dikirimkan ke server melalui protokol TCP/IP. Di server, data terakhir direpresentasikan dalam bentuk GUI sederhana. Langkah-langkah yang dilakukan adalah memprogram modul DT-51 LCMS 2.0, memasang dan menggabungkan modul DT-51 LCMS 2.0 dengan modul wireless YS 1020 RF Data Transceiver serta komputer halte/fakultas, pembuatan program menggunakan bahasa C untuk komputer halte/fakultas dan untuk komputer server.
Hasil pengujian menunjukkan bahwa prototipe sistem pelacak bus kampus Universitas Indonesia ini dapat menampilkan posisi bus kampus dengan cukup akurat, namun masih mempunyai kekurangan yaitu GUI masih sangat sederhana, hanya bisa menampilkan satu bus per satu waktu, dan aplikasinya hanya bisa dijalankan sekali setiap dieksekusi. Dari tanggapan pengguna terhadap sistem ini diketahui bahwa sistem pelacak bus kampus berguna, memiliki GUI yang kurang memenuhi ekspektasi, dan setuju bahwa posisi bus yang ditampilkan cukup akurat.

Campus bus tracking system is an integration of certain softwares and hardwares which can track the position of campus buses and display it to user. This final project will focus on University of Indonesia campus bus, starting from the basic theory about technology used in this system, design of the system, and the testing result with analysis about the system. Besides that, there is a questioner form that will give an abstraction about users' feedback of University of Indonesia campus bus tracking system. Software used in this final project is cygwin as a C compiler. Hardwares used in this system are DT-51 LCMS 2.0 module and YS 1020 RF Data Transceiver wireless module.
DT-51 LCMS module gives an ID for a bus in 8 bit binary. YS 1020 RF Data Transceiver wireless module on the transmitting side forward it and YS 1020 RF Data Transceiver wireless module on the receiving side receive it. YS 1020 RF Data Transceiver wireless module on receiving side installed on a computer is assumed installed on each shelter in University of Indonesia. This computer processes the data and inserts each shelter?s ID. The next process is to forward the final data via TCP/IP to server. In the server, the final data contains bus' ID and shelter's ID represented in a simple GUI. The steps taken are programming DT-51 LCMS module, attaching and integrating DT-51 LCMS 2.0 module and YS 1020 RF Data Transceiver wireless module with computer in the shelter, making program using C for computer in the shelter and for server.
The testing results shows that the prototype of University of Indonesia campus bus tracking system can display the position of campus bus quite accurately but still have some weaknesses. The weaknesses are the GUI is very simple, the GUI can only show a bus in a time, and the application can only run once when executed. Users' feedback about this campus bus tracking system shows that this system is helpful, the design of GUI isn't up to expectation. However, users agree that the position shows in GUI is accurate.

"Wireless receiver architectures and design presents the various designs and architectures of wireless receivers in the context of modern multi-mode and multi-standard devices. This one-stop reference and guide to designing low-cost low-power multi-mode, multi-standard receivers treats analog and digital signal processing simultaneously, with equal detail given to the chosen architecture and modulating waveform. It provides a complete understanding of the receiver‘s analog front end and the digital backend, and how each affects the other. The book explains the design process in great detail, starting from an analysis of requirements to the choice of architecture and finally to the design and algorithm development. The advantages and disadvantages of each wireless architecture and the suitability to a standard are given, enabling a better choice of design methodology, receiver lineup, analog block, and digital algorithm for a particular architecture.
This book is your one-stop reference and guide to designing low-cost low-power multi-mode multi-standard receivers. The material in this book is organized and presented to lead you from applied theory to practical design with plenty of examples and case studies drawn from modern wireless standards."
