Learning Objectives
The objective of the class is to provide the basis of electrical communications with specific reference to the theory of analog and digital modulation and to the reception of signals affected by additive white Gaussian noise.
Prerequisites
It is assumed that the student has a sound understanding of Signal Theory: Fourier theory of deterministic signals (both periodic and aperiodic), random variables, random processes and their spectral analysis
Type of Assessment
Oral exam
Course program
The program is the following:
1) Introduction to communication systems: information and noise, information sources, sketch of a communications system, wireless and wired communications systems, frequency allocations, propagation in wireless communications systems
2) Disturbance over communications systems: band filtered white noise, thermal noise, noise figure and noise temperature, noise figure of cascaded systems
3) Analog modulations: classic AM, AM-DSB, AM-SSB, angle modulations (PM e FM). Modulators and demodulators, performance in noise, threshold effect. Superheterodyne and omodyne receivers. Signal multiplexing: FDM e TDM.
4) Digital modulations. Baseband impulse modulations: "flat top" and "natural gating" PAM, PDM, PPM, quantized impulse modulations, PCM. Line codes: unipolar and bipolar NRZ and RZ. Gray coding. Binary digital modulations: OOK, BPSK, FSK and CPFSK. Relationship between total SNR, SNR per bit and spectral efficiency. Multilevel modulations: M-PAM, M-PSK (QPSK and OQPSK), QAM. Transmission bandwidth and spectral efficiency. Error probability: decision regions and maximum likelihood receiver. Optimum receiver schemes. Error bound.
