Subband analysis and synthesis of real-world textures for objective and subjective determination of roughness

In a previous study we investigated the roughness of real world textures taken from the CUReT database. We showed that people could systematically judge the subjective roughness of these textures. However, we did not determine which objective factors relate to these perceptual judgments of roughness. In the present study we take the first step...

Multiple Subbands Ranging Signals Design and Investigation on Frequency Dependence of the Subband Channel Impulse Responses within an Ultra-wideband Channel

This thesis covers two topics. The first one is signal design for accurate Time-of-Arrival estimation using a number of frequency separated signals. Rather than use a full UWB band, we will use sparse subband signals spanning the full band to construct a new virtual UWB signal. To evaluate the performance of the constructed signal, Cramer-Rao...
