This completely updated second edition of an Artech House classic provides a thorough introduction to the basic principles of electromagnetic wave propagation of radio frequencies in real-world conditions, fully updated by including new achievements in theory and technology. It serves as an invaluable daily reference for practitioners in the field and as a complete, organized text on the subject. This comprehensive resource covers a wide range of essential topics, from the classification of radio waves, electromagnetic wave theory, and antennas for RF radio links, to the impact of the earth surface on the propagation of ground waves, atmospheric affects in radio wave propagation, and radio wave reception. The book explores the propagation of the ground radio waves, namely the waves that propagate in vicinity of the earth's surface (e.g., guided by that interface), without involvement of any atmospheric effects. Specifics of the high-frequency (HF) radio propagation due to reflections from ionospheric layers is studied, based on commonly used models of the ionospheric vertical profiles. Scattering of the radio waves of UHF and higher frequency bands from the random variations of the tropospheric refraction index (from tiny air turbulences) are also considered by using the principles of statistical radio-physics. Analysis of propagation conditions on real propagation paths, including analysis of the power budget of the VHF/UHF link to assure its stability (percentage of availability within observation time frame), terrestrial, broadcast, mobile, and satellite RF links are presented. The engineering design of the cellular networks, including LTE 4G, 5G and upcoming higher generations is explored. HF propagation predictions for extremely long-range links design for commercial and military applications are explained. Packed with examples and problems, this book provides a theoretical background for astrophysical, aeronomy and geophysical instrumentation design.

Based on the popular Artech House classic, Digital Communication Systems Engineering with Software-Defined Radio, this book provides a practical approach to quickly learning the software-defined radio (SDR) concepts needed for work in the field. This up-to-date volume guides readers on how to quickly prototype wireless designs using SDR for real-world testing and experimentation. This book explores advanced wireless communication techniques such as OFDM, LTE, WLA, and hardware targeting. Readers will gain an understanding of the core concepts behind wireless hardware, such as the radio frequency front-end, analog-to-digital and digital-to-analog converters, as well as various processing technologies. Moreover, this volume includes chapters on timing estimation, matched filtering, frame synchronization message decoding, and source coding. The orthogonal frequency division multiplexing is explained and details about HDL code generation and deployment are provided. The book concludes with coverage of the WLAN toolbox with OFDM beacon reception and the LTE toolbox with downlink reception. Multiple case studies are provided throughout the book. Both MATLAB and Simulink source code are included to assist readers with their projects in the field.

Due to the competitions between the telecommunication service providers, the required capacities are increasing all the time. It is important for these providers to develop a network that can transfer more data bytes from one place to another. In addition, the mobile traffic and the internet services need more capacities in the telecommunication networks. Therefore, it is mandatory for the networks to handle large amounts of data in a fast and a reliable way. Of course, one possibility would be Ethernet traffic, but in cellular transmission networks there are a strict requirement for delay, data loss and synchronization and this is why the Ethernet is not yet supported.The Synchronous Digital Hierarchy (SDH) is one answer for increasing the network data traffic. For example, if we need to transfer 63 × 2.048 Mb/s (E1) signals from one place to another a huge amount of wires will be needed, on the other hand the SDH needs only two fibers to do the same operation. Many vendors have a product called STM1 multiplexer and its functionality to add and drop 63 × 2.048 Mbit/s into 155.52 Mbit/s (STM-1). The bit rates of the basic signals in the SDH are derived from the same clock source, which means that the SDH is completely synchronous transmission system. SDH has many different hierarchy levels starting from 155.52 Mbit/s to 10 Gbit/s and the STM-1 with a bit rate of 155.52 Mbit/s is the basic module of the SDH system. The SDH signal is terminated to E1 (2.048 Mbit/s) signals by using terminal multiplexer.Before the SDH multiplexer operates in the telecommunication market, there is a huge amount of work to put the requirements specifications, by studying the reality of the market needs. Many chip manufacturers have SDH chips in their product catalog, so one has to make a decision which manufacturer's chip to use. In addition, one must decide how to handle overhead bytes and how to implement all this in network manager software. After all these decisions, we have a huge amount of data and the last thing to do is to decide which features are implemented and which are not. Because of time-to-market pressures, the implementation has to be phased and the first phase must contain only the necessary functionality and nothing more to reduce the development time to minimum.The Synchronous Digital Hierarchy (SDH) multiplexers form the core part of the backbone telecommunication networks, and the effective design, reliability analysis and training are essential to managing SDH network effectively. Today and shortly, the demands to transfer a tremendous mass of data among the various applications in many fields inside the country become an exclusive responsibility particularly with the significant developments of the clouding policies in the different forms such the data centers and the implementations of many smart applications of the 5G in the various areas of the information technologies. The current design of the core communication network consists of 3 independent zones, the 1'st zone is layer 1 and layer 2 which recognized as the physical layer of the core optical network such Optical Transport Network (OTN), the 2'nd band is layer 3 which viewed as IP core network, and the last zone is the access and the application layers such 4G network. The challenge in the current communication model is no associations among these 3 zones of the communication network to optimize the capacities and the needed resources which are required to carry the data among any of them. Now the optical transport network (OTN) represents the critical point of carrying a tremendous amount of data for the mobile network such 4G between the different sites.
