Recently, the OFDM technology has advanced significantly. It has found applications in 5G using concepts such as OFDM-MIMO, Massive MIMO and others. However, OFDM is still the fundamental building block of all these advanced applications. To help the readers get up to speed in stepping into the 5G era, this book entitled “Introduction to OFDM …
The Technical Foundations of IoT by Boris Adryan, Dominik Obermaier, Paul Fremantle provides an overview of the technical aspects of the Internet of Things (in fact, most other modern technology!), offering more theory and background information than is usually required for non-specialists in interdisciplinary development teams. That is, product design specialists are going to get an introduction …
Once in a while we find ourselves writing about topics which are relatively new to us. My comfort zone as an author is RF engineering but suddenly it seems that free space optical wireless is becoming important in space and terrestrial networks. Counter intuitively this became obvious when looking at the economics of subsea fibre …
At Artech House, we ask our authors what problems their books can help readers solve. In this series, we share what our authors aim to do in their writing. Read on to find out what Barbara Kemp and Bart Lovett, who wrote The Handbook of Next-Generation Emergency Services, had to say: What are some problems your …
This book is the definitive resource for in-band full-duplex (IBFD) wireless systems. IBFD technology allows devices to transmit and receive signals on the same frequency at the same time, but has intentionally been avoided in a wide range of traditional systems. This is due to the significant self-interference that is generated by a transmitter co-located …
We’re thrilled to share the latest in communications and photonics from Artech House – click here for our new brochure.
Sometimes as engineers we get depressed by the marketing hype applied to what are perceived as new technology opportunities. Smart Cities are an exemplar of this problem. A local satirical journalist used to point out that the easiest way to uncover absurdity was to proposition the opposite, for example, ‘Dumb Cities, the future?’ But there …
The Long Read Every so often we find ourselves embarking on a small piece of research that explodes into a major project. This happened to me this month after a chance encounter with a neighbour who is a senior strategist for one of the oil majors. We were talking about the electric car that sits …
Waves, either electromagnetic (EM) or acoustic (AC) interact with objects and scatter. The addition of incident and scattered fields form the total fields. Scattered fields include (but not limited with) reflections, refractions, and diffractions. The Handbook of Next Generation Emergency Services by Barbara Kemp and Bart Lovett is about diffraction modeling and simulation. Scattering has gained …
A Geographic Information System (GIS) is a computer system that gathers, analyses, stores, checks, manipulates, manages, and visualizes data related to spatial locations on Earth’s surface. A GIS works as a database with geographic information (alphanumeric data) that is associated by an identifier common to the graphic objects of digital maps. In this way, when …
