Design and implementation of a communication system for Poor Quality Communication
Channels using MATLAB
INTRODUCTION
Communication systems obtain data or message signals from a sender. The message
signal is fed into a transmitter and the transmitter modulates the signal so that it can be
transmitted over the communication channel as chosen by the users. There are common phases in
the communication system namely the transmitter, the channel, and the receiver. The transmitter
receives the message and passes it through a mixer and it performs modulation of the signal
before sending it out to the antenna for transmission via radio signals or through a wired channel.
The transmitter is a collection of electronic components and circuits that convert the electrical
signals into a signal suitable for transmission over a given medium. The transmitters are made up
of oscillators, and amplifiers, tuned circuits and filters, modulators, frequency mixers, frequency
synthesizers, and other circuits.
The receiver section has amplifiers, oscillators, mixers, tuned circuits, and filters with a
demodulation or message detector that seeks to recover the original intelligence signal from the
