Experimentally Detecting IEEE 802.11n Wi-Fi Based on Cyclostationarity Features for Ultra-Wide Band Cognitive Radios
In this paper we present some experimental results
on the cyclostationarity properties of the IEEE802.11n Wi-Fi
transmissions, and the usage of the cyclostationarity features to
detect IEEE802.11n radios in the context of ultra wide band
(UWB) based cognitive radios (CR). The IEEE 802.11n lies
in the UWB frequency range, at 5.2GHz, and the CR needs
to successfully detect the legacy user to avoid interference.
By performing cyclostationarity analysis we compute the cyclic
power spectrum (CPS) of the IEEE802.11n transmissions and
use it for detecting the presence of the legacy user. We conduct
experimentations to perform our study under different channel
conditions and perform post signal analysis to measure the
detection performance using the CPS based detection technique.
The probability of false alarm and the probability of missed
detection are computed and the results are presented for different
channel conditions, together with the CPS of the legacy user¿s
signal.
