Subject of the course content: Brief revue of signal models. Definitions and basic properties of discrete transforms. Orthogonal discrete transforms: Fourier(DFT), Hartley(DHT), Karhunen-Loeve (KLT), Cosine (DCT), Lapped (LOT), wavelet(WLT), Walsh-Hadamard (WHT). Two- dimensional transforms. Fast algorithms: concept and selected examples. Applications in signal processing: filtering, spectral estimation, coding, adaptive filtering, multirate signal processing.
Introduction to the fundamental theory of multirate signal processing: decimation, interpolation, and sampling rate conversion, Two-channel filter banks: quadrature-mirror filter banks (QMF), perfectly reconstructing, paraunitary, biorthogonal and linear phase filter banks, M-channel filter banks used as subband coding or transmultiplexing filter banks. Polyphase structures for two-channel and M-channel filter banks. Lattice structures for Linear Phase PR QMF Banks, Discrete Wavelet Transform (DWT) and its relations to multirate filter banks. The Short-Time Fourier Transform. The Wavelet Transform. Discrete-Time Orthonormal Wavelets. Continuous-Time Orthonormal Wavelet Bases. Lifting implementations of wavelet transform Applications of wavelets for signal analysis and compression.
