Mobile Broadcasting with WiMAX Principles
This book is exclusively dedicated to WiMAX. The focus of the book is<br />
on the applications of WiMAX networks, with delivery of multimedia<br />
content to wireless and mobile devices being the ar
Mobile and Wireless Communications
There are few technologies that have had a more profound effect on people’s lives<br />
than mobile communications. As recently as twenty years ago no one had a mobile<br />
phone, while today 1.4 bil
LTE, WiMAX and WLAN
For nearly a hundred years telecommunications provided mainly voice services and very low speed<br />
data (telegraph and telex). With the advent of the Internet, several data services became mainstre

To meet the future demand for huge traffic volume of wireless data service, the research on the fifth generation<br />
(5G) mobile communication systems has been undertaken in recent years. It is expe
Hybrid+Analog-Digital+Precoding
In this paper we revisit hybrid analog-digital precoding systems with emphasis on their modelling<br />
and radio-frequency (RF) losses, to realistically evaluate their benefits in 5G system implement
