- W2375994662 abstract "The technique that improves time-frequency representation using digital image processing methods is introduced. The combination of the 2-D smoothing operation, the threshold comparison and the selection of the peaks of time-frequency distribution can lead to the improved time-frequency representation with high concentration and the noise suppression. Compared with traditional methods such as the design of computational kernel and operations in ambiguity domain, it requires no prior knowledge of the signal. This conclusion can be applied to signal separation and parameter identification. It can also be used in the estimation of direction of arrival (DoA) with wideband signal. The effectiveness of the technique is demonstrated by the simulations." @default.
