书籍 MIMO-OFDM Wireless Communications with MATLAB
MIMO-OFDM is a key technology for next-generation cellular communications (3GPP-LTE,
Mobile WiMAX, IMT-Advanced) as well as wireless LAN (IEEE 802.11a, IEEE 802.11n),
wireless PAN (MB-OFDM), and broadcasting (DAB, DVB, DMB). This book provides a
comprehensive introduction to the basic theory and pra ...
书籍 Mobile Radio Channels
With this book at your fingertips, you, the reader, and I have something in common. We share
the same interest in mobile radio channels. This area attracted my interest first in autumn 1992
whenImovedfromindustrytoacademiatofindachallengeinmylifeandtopursueascientific
career. Since then, I consider ...
书籍 Opportunistic+Spectrum+Sharing
Rapid growth of wireless communication services in recent decades has created
a huge demand of radio spectrum. Spectrum scarcity and utilization inefficiency
limit the development of wireless networks. Cognitive radio is a promising tech-
nology that allows secondary users to reuse the underutilized ...
