Content(s)
Global scheme of information digital transmission chain
Baseband digital Modulation
Carrier frequency digital modulation
- Linear modulations (ASK, PSK, QAM), cyclo-stationnarity, average Power Spectral Density, ... Energy per bit, ...
- differential codding: goal and pronciple
- Non-linear modulations (FSK, CP-FSK).
Optimal Coherent receiver for Additive White Gaussian Noise.
- Correlator (Matched Filter and timing for sampling)
- Inter-Symbols Interference (Nyquist cristerium)
- Band-limited transmission (root raised cosine filter, minimal bandwith)
- Performances (spectral efficency, bit error rate vs Eb/N0, link with Information Theory limits.
