Smart Spectrum from Space with Geoff Varrall

What did Galileo and Karl Jansky have in common? In 1610, Galileo looked up at the stars through his latest invention, a prototype for the modern day refractor telescope. In 1931 Karl Jansky accidentally discovered radio astronomy when investigating background static on Bell Labs short wave transatlantic radio phone service. Radio astronomers explore the outer …

Investigating High-Thoroughput Satellites with Hector Fenech

The satellite communication landscape is evolving. The traditional services are not sustaining the growth that the space industry is used to, and new services are showing new promises. Broadband access is such an area encompassing two main applications, namely fixed broadband and mobile broadband. In these days where economics are becoming the deciding factor in …

Why You Need This Book: Introduction to OFDM Receiver Design and Simulation with Y.J. Liu

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 …

That is, product design specialists are going to get an introduction …

Smart Fibre from Space – Moving the Internet into the Galaxy? with Geoff Varrall

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 …
