Simulation And Design Of Communication Systems
Based
On MATLAB
Abstract
Communication is through a media for transportation. Communication
system which is used to complete the process of information transmission systems ,in
general, is to send the information from the source to one or more destinations.
Modulation and demodulation occupied an important position in the transmission of
information which is essential, so the research about the modulation and demodulation
process in the communication system is extremely important. MATLAB is a numerical
computation, graphics rendering, image processing and system simulation and other
powerful features in one of the scientific computing language, it is a powerful matrix
calculation and graphical visualization features and a rich toolbox provides a great
convenience for the communication system of modulation and demodulation process.
This paper introduces the concept of the communication system, and then leads to
modulation and demodulation, and then introduced several of our commonly used method
of modulation and demodulation. As the power of MATLAB so we introduced the
communication system toolbox in the MATLAB. We gives several examples about the
communication system based on MATLAB modulation and demodulation and use the
software of MATLAB to simulate them.
