We propose a time-frequency (TF) technique designed to match signals with multiple and different characteristics for successful analysis and classification. The method uses a modified matching pursuit signal decomposition incorporating signal-matched dictionaries. For analysis, it uses a combination of TF representations chosen adaptively to provide a concentrated representation for each selected signal component. Thus, it exhibits maximum concentration while reducing cross terms for the… CONTINUE READING
