Available in PDF, EPUB and Kindle. Book excerpt: Utilizing multidimensional signaling techniques, a generalized multirate wavelet-based modulation format for orthogonally multiplexed communication systems is presented. Wavelet Packet Modulation (WPM) employs the basis functions from an arbitrary pruning of a dyadic tree structured filter bank as orthogonal pulse shapes for conventional Quadrature Amplitude Modulation (QAM) symbols. This generalized framework affords an entire library of basis sets with increased flexibility in time-frequency partitioning. The bandwidth efficiency and power spectral density for the general signal have been analytically derived and it is shown that these figures of merit, for every possible permutation of wavelet packet filter banks, are equivalently that of standard QAM. Hence, WPM is directly applicable in all existing systems employing this modulation format, with the added benefit of arbitrary time- frequency plane configurations. This benefit is not to be understated - flexibility in both time and frequency are extremely important for mitigating certain types of channel impairments, e.g. hostile narrowband and/or impulsive jamming/countermeasures. The fact that, by a simple hardware exchange, this flexibility is afforded for communication links currently in operation is of critical value to DoD-wide communication system designers. The following report details the work accomplished for this project - a survey of relevant work, wavelet packet modulation, the discrete implementation of WPM, and the spread spectrum extension of WPM.

Download or read book Wireless Transceiver Architecture written by Pierre Baudin and published by John Wiley & Sons. This book was released on 2014-12-15 with total page 752 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fully comprehensive reference combining digital communications and RFIC (Radio Frequency Integrated Circuits) in one complete volume There are many books which focus on the physical implementation of the RF/analog part of transceivers, such as the CMOS design, or the signal processing involved in digital communications. However, there is little material dedicated to transceiver architecture and system design. Similarly, much of the existing literature looks at concepts useful for dimensioning, yet offers little practical information on how to proceed for dimensioning a line-up from scratch, and on the reasons for proceeding that way. This book redresses the balance by explaining the architecture of transceivers and their dimensioning from the perspective of a RFIC architect from within industry. It bridges the gap between digital communication systems and radiofrequency integrated circuit design, covering wireless transceiver architecture and system design from both system level and circuit designer aspects. • Covers digital communication theory, electromagnetism theory and wireless networks organization, from theories to implementation, for deriving the minimum set of constraints to be fulfilled by transceivers • Details the limitations in the physical implementation of transceivers to be considered for their dimensioning, in terms of noise, nonlinearity, and RF impairments • Presents transceiver architecture and system design in terms of transceivers budgets, transceivers architectures, and algorithms for transceivers

This book was released on 2015-09-29 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates and discusses the hardware design and implementation to achieve smart air interfaces with a reduced number of Radio Frequency (RF) transmitter and receiver chains, or even with a single reconfigurable RF-Frontend in the user terminal. Various hardware challenges are identified and addressed to enable the implementation of autonomous reconfigurable RF-Frontend architectures. Such challenges are (i) the conception of a transceiver with wide tuning range of at least up to 6 GHz, (ii) the system integration of reconfigurable technologies targeting current compact devices that demand voltages up to 100 V for adaptive controlling and (iii) the realization of a multiband and multistandard antenna module employing agile components to provide flexible frequency coverage. A solid design of a reconfigurable frontend is proposed from the RF part to the digital baseband. The system integration of different components in the reconfigurable RF-Frontend of a portable-oriented device architecture is demonstrated.
Download or read book Circuits for MM wave Radio and Radar Transceiver Front Ends written by Ekaterina Tyshchenko and published by . This book was released on 2011 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents the design and implementation of 140 GHz to 170 GHz transceivers in SiGe HBT technologies and a 95 GHz receiver in 65 nm CMOS technology. Optimization and modeling of all passive components and transistor biasing at peak-fT and peak-f MAX current densities are employed to obtain higher frequency operation of circuit blocks compared to state of the art. These circuit blocks include static and dynamic frequency dividers, voltage-controlled oscillators, and tuned mm-wave amplifiers. Design procedures for a 100 GHz static divider, a 136 GHz dynamic divider, as well as low-power divider topologies are presented. A methodology for the design of quadrature voltage-controlled oscillators in CMOS and SiGe technologies is described, together with a technique for reduced-power LO-path design. Tuned 5-stage 140 GHz, 160 GHz, and 170 GHz amplifiers with more than 15 dB in SiGe HBT technology are reported.Using these circuit building blocks, a 95 GHz receiver in 65 nm CMOS technology with 12.5 dB gain, 7 dB noise figure, and 206mW. Also, several 165 GHz transceivers are implemented in SiGe HBT technology. The 165 GHz transceivers that include an oscillator, a divider, RX, LO, and TX amplifiers, and a mixer, were designed with and without on-chip antennas. They have -3 dB conversion gain, all achieved at RF, and -3.5 dBm output power. Following that, a 140 GHz fully-integrated transceiver and a 140 GHz transceiver array with on-chip patch antennas were designed in a 0.13micron SiGe BiCMOS technology, demonstrating the highest integration levels at this frequency in silicon to date. These transceivers feature 136-145 GHz voltage-controlled oscillators, 20 dB receive-amplifiers and mixers,transmit-amplifiers with amplitude-shift keying modulation, and variable-gain IF amplifiers. At 140 GHz the transceivers have up to 32 dB conversion gain and -8 dBm output power. Wireless data transmission at 4 Gb/s was demonstrated over 1.15m with off-chip horn antennas, and over 2 cm with the on chip antennas. With on-chip antennas, the transceiver could detect a Doppler shift of as little as 25 Hz. Both transceivers were also operational in frequency-modulated continuous-wave radar mode.
