Aim: The
course is intended to give a survey of the basic aspects of signal domains and
the effects in digital signal processing in terms of signal distortion.
Topics:
1. Review
of some notions on Fourier Transform in different time domains (continuous and
discrete; aperiodic and periodic). The FFT.
2. Definitions
and properties of signal energy, convolution, correlation in the time domains
and their Fourier transforms
3. Signal
transformations. Linear transformations. Elementary transformations: sampling
and interpolation. Up- and Down-Periodization
4. Numerical
computation of the Fourier transform of a continuous-time finite energy signal
via FFT
5. Numerical
computation of the convolution (correlation) of two continuous-time finite
energy signals via FFT.
6. Bandlimited
continuous time signal filtering: from analog filters to a mix of analog and
digital filters.
7. Example
of applications: OFDM modulation and cyclic prefix.
8. Channel
estimation in OFDM systems
9. Estimate
of power spectrum for finite power signals. From definitions to numerical
computation.
10. FFT
output SNR for a quantized input signal. Discussion
Course

Basic knowledge of signals and systems.
