Fundamentals of multirate systems
Subsampler, expander, polyphase representation, efficient structures for
decimation and interpolation filters
2. Maximally decimated filter banks
Amplitude and phase distortion of multirate systems, alias-free filter bank,
perfect reconstruction filter banks
3. Paraunitary filter banks
Lossless systems, 2 and M channel paraunitary filter banks, lattice structures,
lapped orthogonal transform
4. Subband/wavelet coding and transform coding
Quantizations, SNR maximization, Karhunen-Loeve transform, wavelet
5. Image and Audio Compression
JPEG, MP3, Embeded Zerotree Wavelet (EZW) and SPIHT algortihms for image coding
6. Discrete Multitone (DMT) modulation
7. Wavelet transform and filter banks
Short-time Fourier transform (STFT), advantages of wavelets over STFT,
relation between wavelets and filter banks
