This is an analog signal communication simulator, usign frequency modulation. It is designed in MATLAB-Simulink. The COMMUNICATIONs channel beetween the transmitter and the reciever is supposed to be affected by additive white Gaussian noise.

From the transition of analog to digital communication along with seamless mobility and
high computing power of small handheld devices, the wireless COMMUNICATIONs industry has
seen tremendous changes leading to the integration of several telecommunication networks,
devices and services over last 30 years. The rate of this progress and growth has increased
particularly in the past decade because people no longer use their devices and networks for
voice only, but demand bundle contents such as data download/streaming, HDTV, HD video ,
3D video conferencing with higher efficiency, seamless connectivity, intelligence, reliability
and better user experience. Although the challenges facing service providers and
telecommunication companies differ by product, region, market size, and their areas of
concentration but time to market, efficient utilization of their assets and revenue expansion,
have impacted significantly how to manage and conduct their business while maintaining
sufficient margin.
The current methods of COMMUNICATIONs are becoming less relevant under
today’s growing demand for and reliance on constant connectivity. Of
decreasing relevance are the models of a single radio to perform a single
task. The expansion of wireless access points among coffee shops, airports,
malls, and other public arenas is opening up opportunities for new services
and applications.
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 efficiency to its limit.
The past decades have witnessed wide demand and applications for wireless commu-
nications in the human body area, that is, in the immediate environment around a
human body. These demands and applications especially focus on wireless transmis-
sion and networking of personal information for user identification, healthcare and
medical applications.
The very title of this book is borrowed from the information theory vocabulary,
and, quite naturally, it is an outline of this theory that will serve as an introduction.
The subject of information theory is the scientific study of COMMUNICATIONs. To this
end it defines a quantitative measurement of the communicated content, i.e. informa-
tion, and deals with two operations essential for communication techniques: source
coding and channel encoding.
