Analysis/Synthesis filter bank design based on time domain aliasing cancellation

摘要: A single-sideband analysis/synthesis system is proposed which provides perfect reconstruction of a signal from set critically sampled analysis signals. The technique developed in terms weighted overlap-add method and allows overlap between adjacent time windows. This implies that domain aliasing introduced the analysis; however, this cancelled synthesis process, can provide reconstruction. Achieving places constraints on window shape are equivalent to those placed frequency channels used recently systems based cancellation [7], [8]. In fact, duality exists new techniques [7] [8], more efficient than designs for given number channels, reasonably band-limited channel responses. could be particularly useful applications where desirable, e.g., coding.
