Learning Outcomes

Understanding the basic principles of Communication Systems and acquiring essential knowledge and skills regarding the design of Digital Telecommunication Systems.

Indicative Module Content

  • Sources of information, entropy, and coding.

  • Nyquist theorems (regarding the required bandwidth).

  • Analog to digital conversion: Pulse Code Modulation (PCM), Differential Pulse Coding (DPCM), and Delta modulation (DM).

  • Introduction to the concept of noise and noise channel modeling (Gaussian white noise additive, AWGN).

  • AWGN channel capacity.

  • Baseband digital transmission techniques: Pulse Amplitude Modulation (PAM) and Pulse Position Modulation (PPM).

  • Optimal detector design for digitally modulated signals in the presence of Additive White Gaussian Noise.

  • Intersymbol interference phenomenon and its elimination with raised cosine filters.

  • Passband digital modulation techniques: Phase shift keying (PSK), Phase shift and amplitude modulation (QAM), frequency-shift keying (FSK).

  • Error probability of digital modulation techniques
