​ This updated book, reconfigured as a textbook, covers the key technologies associated with the physical transmission of data on 5G mobile systems. Following an updated overview of these technologies, the author provides a high-level description of 3GPP’s mobile communications standard (5G NR) and shows how the key technologies presented earlier facilitate the transmission of very high-speed user data and control data and can provide very low latency for use cases where this is important. In the final chapter, an overview and the physical layer aspects of 5G NR enabled Fixed Wireless Access (FWA) networks is presented. Material in the first edition addressed mainly the key physical layer technologies and features associated with 3GPP release 15, the first release to support 5G. This edition adds descriptions of some of the technological advancements supported in release 16, including integrated access and backhaul (IAB), sidelink communication, NR positioning, operation in unlicensed bands, and multiple transmission points transmission. This textbook is intended for graduate and upper undergraduate engineering students and practicing engineers who have an interest in 3GPP’s 5G enabled mobile and or FWA networks and want to acquire, where missing, the necessary technology background in order to understand 3GPP’s physical layer specifications and operation. The author provides working problems and helpful examples throughout the text.

Sequential decoding of convolutional coded data offers essentially error-free communication at rates within 1/3 of channel capacity, thus making it attractive for space and other communication systems. Sequential decoding is a sub-optimum decoding technique that sequentially estimates transmitted symbols, using an appropriate confidence measure or metric. An a posteriori probability metric has been generally employed. However, the derivation of this metric, the exact system performance, and the operational sensitivity of a sequential decoded to the choice of its metric have not been adequately treated. This paper determines a sequential decoder's performance and metric sensitivity by means of a computer simulation using two metrics: (1) A log-a-posteriori probability metric, and (2) A cross-correlation metric. Both metrics are defined, derived, and tabulated for the memory-less Gaussian channel. Simulations of a rate 1/2, constraint-length 32 coded data system are made using 16 level quantized metrics. When good metric and decoder parameters have been found, the decoder's computational load, overflow probabilities, and error probability are found as a function of channel signal-to-noise ratio, using at least 500 simulated telemetry frames per data point. It is shown that the correlation metric is inferior to the probability metric by at least 1.5 decibels and suffers a higher error rate. In addition, the correlation metric decoder degrades intolerably with 0.5 decibel signal-amplitude fluctuations, whereas the probability metric decoder is negligibly affected.

Rubrics offer concrete artefacts of what schools evaluate to be of merit, and what educators and schools value to be worth rewarding. Assessment Rubrics Decoded offers insights into a myriad of issues that affect, and are affected by, the construction of merit in students’ learning and the articulation of (underlying) educational ideologies in the assessment of student achievement. Designed for both students and teachers – who should have parity of involvement in developing and using rubrics – this book covers the problematic issues of assessment in schools while offering readers practical solutions to navigating the ensuing tensions and dilemmas. The notion that rubrics may hinder assessment transparency is also discussed, with examples, to warn against uncritical use of rubrics that may discipline rather than help learners. The perspective of a school leader in providing assessment leadership to rubrics usage across a school is included for extending awareness of rubrics beyond classroom contexts. This provides an informed approach for teachers to understand the stakes and complexities involved in judging learning, and learners, whilst offering concrete options and suggestions to consider. This book will be a valuable resource for classroom teachers, school leaders, teacher educators and researchers interested in the field of assessment rubrics.

The wireless medium is a shared resource. If nearby devices transmit at the same time, their signals interfere, resulting in a collision. In traditional networks, collisions cause the loss of the transmitted information. For this reason, wireless networks have been designed with the assumption that interference is intrinsically harmful and must be avoided. This book, a revised version of the author's award-winning Ph.D. dissertation, takes an alternate approach: Instead of viewing interference as an inherently counterproductive phenomenon that should to be avoided, we design practical systems that transform interference into a harmless, and even a beneficial phenomenon. To achieve this goal, we consider how wireless signals interact when they interfere, and use this understanding in our system designs. Specifically, when interference occurs, the signals get mixed on the wireless medium. By understanding the parameters of this mixing, we can invert the mixing and decode the interfered packets; thus, making interference harmless. Furthermore, we can control this mixing process to create strategic interference that allow decodability at a particular receiver of interest, but prevent decodability at unintended receivers and adversaries. Hence, we can transform interference into a beneficial phenomenon that provides security. Building on this approach, we make four main contributions: We present the first WiFi receiver that can successfully reconstruct the transmitted information in the presence of packet collisions. Next, we introduce a WiFi receiver design that can decode in the presence of high-power cross-technology interference from devices like baby monitors, cordless phones, microwave ovens, or even unknown technologies. We then show how we can harness interference to improve security. In particular, we develop the first system that secures an insecure medical implant without any modification to the implant itself. Finally, we present a solution that establishes secure connections between any two WiFi devices, without having users enter passwords or use pre-shared secret keys.

Covering the full range of channel codes from the most conventional through to the most advanced, the second edition of Turbo Coding, Turbo Equalisation and Space-Time Coding is a self-contained reference on channel coding for wireless channels. The book commences with a historical perspective on the topic, which leads to two basic component codes, convolutional and block codes. It then moves on to turbo codes which exploit iterative decoding by using algorithms, such as the Maximum-A-Posteriori (MAP), Log-MAP and Soft Output Viterbi Algorithm (SOVA), comparing their performance. It also compares Trellis Coded Modulation (TCM), Turbo Trellis Coded Modulation (TTCM), Bit-Interleaved Coded Modulation (BICM) and Iterative BICM (BICM-ID) under various channel conditions. The horizon of the content is then extended to incorporate topics which have found their way into diverse standard systems. These include space-time block and trellis codes, as well as other Multiple-Input Multiple-Output (MIMO) schemes and near-instantaneously Adaptive Quadrature Amplitude Modulation (AQAM). The book also elaborates on turbo equalisation by providing a detailed portrayal of recent advances in partial response modulation schemes using diverse channel codes. A radically new aspect for this second edition is the discussion of multi-level coding and sphere-packing schemes, Extrinsic Information Transfer (EXIT) charts, as well as an introduction to the family of Generalized Low Density Parity Check codes. This new edition includes recent advances in near-capacity turbo-transceivers as well as new sections on multi-level coding schemes and of Generalized Low Density Parity Check codes Comparatively studies diverse channel coded and turbo detected systems to give all-inclusive information for researchers, engineers and students Details EXIT-chart based irregular transceiver designs Uses rich performance comparisons as well as diverse near-capacity design examples
