Objectives
- To be able to explain the role of the different elements in a communication channel allowing to transmit a digital information.
- To be able to analyze a basic digital transmission channel (modulation/demodulation on a Additive white Gaussian noise channel) in terms of spectral and power efficiencies.
- To be able to implement basic digital transmission channels, to compare and optimize them in terms of spectral and power efficiencies.
Description
1- Role of the different elements in a communication channel allowing to transmit a digital information.
2- Generation of a signal allowing to transmit a binary information (digital modulation) :
- for a baseband transmission,
- for a transmission on a carrier frequency (ASK, PSK, QAM modulations),
- notion of spectral efficiency.
3- Basic modulation for the transmission channel.
4- Definition of an optimized digital demodulator :
- power efficiency,
- interference between symbols and Nyquist criterion,
- matched filtering.
5- Bit error rate computation.
6- Notion of complex enveloppe and equivalent lowpass channel for transmissions on carrier frequencies.
7- Example of a basic digital transmission channel : DVB-S physical layer.
Targeted skills
Understand the role of the differents elements in a communication channel allowing to transmit a digital information.
Being able to implement and optimize the modulator/demodulator of a communication channel allowing to transmit a digital information when the channel is an AWGN (Additive White Gaussian Noise) channel.
