چكيده فارسي :
In this paper, a fuzzy c-means algorithm is proposed
for jamming detection at the base station in cellular networks.
The jamming detection process itself uses an improved LCR
based Doppler shift estimation algorithm by using only inherent
information which is available in common receivers without any
excessive hardware requirements. The estimation of channel
Doppler shift at base station in cellular networks helps base
stations in channel estimation, which effectively improves
jamming detection performance. The performance of the
proposed algorithm in a TETRA network is modeled and
simulation shows acceptable results in a wide range of user
terminal velocities.
