Matlab based communication projects

To convey a signal from the transmitter to receiver communication channel is required. The daily information transmission is supported mostly by digital communication system such as telephone channels, satellite channels, microwave radio etc.

Characterizing of gathered idea source and source encoding has a reasonable beginning in introduction of digital communication systems design and analysis electrical communication system elements

• Receiver
• Channel
• Transmitter
• Output Transducer
• Input Transducer

In many areas digital communication has its uses Digital-to-Analog converter (DAC) is needed for the transmitter where as Analog-to-Digital converter (ADC) is required for receiver. We could use phase-shift keying (PSK) for deep space communication where power efficiency plays a vital part.

The functional task which is carried out at the transmitter and the receiver must add message signal discretization and expand at transmitter and message signal synthesis or outburst  the receiver are done in digital communication system.

Electromagnetic wave propagation through space is used for communication. Components of digital communication system.

• Digital modulator
• Channel encoder
• Channel decoder
• Source decoder
• Digital demodulator

Seven groups of transforming digital communication

• Spreading
• Synchronization
• Encryption
• Channel coding
• Modulation / Demodulation
• Formatting and source coding
• Multiple accesses & Multiplexing

To predict channel distortion an adaptive filter is used in communication system.
