Interference in IEEE 802.11 WLANs

This book characterizes various signals found in
Wi-Fi networks. In particular, it analyzes
Barker-spread signals, Complementary Code Keying
signals, Orthogonal Frequency Division Multiplexed
signals with Cyclic Prefix Code, and Microwave oven
signals. Experimental and simulation results are
utilized to refine and verify the theoretical models
that use the specifications of the IEEE 802.11b/g
standards throughout the book. The wireless
interference resulting from intentional and
unintentional sources is characterized and mitigated
to provide better spectrum efficiency and dynamic
resource allocation in WLANs. While Adaptive
Antennas with Tapped Delay Lines are suggested to
mitigate intentional interference from Wi-Fi sources,
other mitigation methods are proposed to allow for
WLAN operation in the presence of unintentional
interferers like microwave ovens. The OFDM and
cyclic prefix code analysis presented by this book
relates to many applications beyond Wi-Fi networks.
For example, it applies to WiMAX and DSL networks,
digital television, and audio broadcasting. This book
is particularity useful to researchers, R&D
companies, RF engineers, and telecommunications
professionals.
