Use
the fast Fourier transform function fft to analyse following signal. Plot the original signal, and the magnitude of its
spectrum linearly and logarithmically. Apply Hamming window to reduce the
leakage.
.
The hamming window can be coded in Matlab ...

Licensed spectrum remains 3GPP operators’ top priority to deliver
advanced services and user experience
Opportunistic use of unlicensed spectrum is becoming an important
complement for operators to meet the growing traffic demand
Moving forward 3GPP operators will have two options to offload
traffi ...
The growing interest for high data rate wireless communications over the last few decades
gave rise to the emergence of a number of wideband wireless systems. The resulting scarcity
of frequency spectrum has been forcing wireless system designers to develop methods that
will push the spectral effici ...
According to the statistics of the Federal Communications Commission
(FCC), temporal and geographical variations in the utilization of the as-
signed spectrum range from 15% to 85%. The limited available radio spec-
trum and the inefficiency in spectrum usage necessitate a new commu-
nication paradi ...
Cognitive radio has emerged as a promising technology for maximizing the utiliza-
tion of the limited radio bandwidth while accommodating the increasing amount of
services and applications in wireless networks. A cognitive radio (CR) transceiver
is able to adapt to the dynamic radio environment and ...
This book examines the technologies underlying the compression and trans-
mission of digital video sequences over networking platforms. The incorporated
study covers a large spectrum of topics related to compressed video communica-
tions. It presents to readers a comprehensive and structured analysi ...
