Binary offset carrier (BOC) signal synchronization is one of the most important steps to recover the navigation data in global navigation satellite system (GNSS) including Galileo and global positioning system (GPS). The main error sources in synchronizing BOC signals are the multiple side-peaks in the BOC autocorrelation and the multipath delay. Recently,(More)
In this paper, we propose two new stereo confidence metrics which are used for estimating the reliability of a stereo matching result more accurately. Unlike the conventional metrics which exploit the cost information of the pixel being processed only, the proposed metrics utilize the cost information of the surrounding pixels as well as the pixel being(More)
BACKGROUND & AIMS Hepatic ischemia/reperfusion (I/R) injury may activate innate immunity through the interaction of toll-like receptor 4 (TLR4) with endogenous ligands. Omega-3 polyunsaturated fatty acids (ω-3 PUFAs) exert suppressive effects on innate immunity through various mechanisms. In this study, we investigated the effect of dietary supplementation(More)
Due to multiple side-peaks in the binary offset carrier (BOC) autocorrelation function, BOC signal synchronization is one of the most challenging tasks for global navigation satellite systems (GNSSs) including Galileo and global positioning system (GPS). Recently, a novel correlation function with reduced side-peaks was proposed for BOC signal(More)
A new method of pruning redundant synthesis unit instances in a large-scale synthesis database was proposed based on weighted vector quantization (WVQ). WVQ takes relative importance of each instance into account when clustering the similar instances using vector quantization (VQ) technique. The proposed method was compared with two conventional pruning(More)
Binary offset carrier (BOC) signal tracking is one of the challenging problems in future Global Navigation Satellite Systems (GNSS) including Galileo and Global Positioning System (GPS), because false lock could be generated in the tracking procedure due to multiple side-peaks in BOC autocorrelation. Multipath mitigation is another challenging problem in(More)
In this paper, we propose a new model for synthesizing fundamental frequency (F0) contours using a stylization and a neural network learning method. The F0 contour is described as the superposition of 4 layered features; global tune, word pitch bias, lexical tone, and the syllabic pitch pattern. We rstly stylize the F0 contour of speech material, and(More)
Binary offset carrier (BOC) signal synchronization is based on the correlation between the received and locally generated BOC signals. Thus, the multiple side-peaks in BOC autocorrelation are one of the main error sources in synchronizing BOC signals. Recently, a new correlation function with no side-peaks was proposed for sine or cosine phased BOC signal(More)
Binary offset carrier (BOC) signal synchronization is one of the most important steps to recover the transmitted information in a global navigation satellite system (GNSS) such as Galileo and global positioning system (GPS). Generally, BOC signal synchronization is achieved based on the correlation between the received and locally generated BOC signals.(More)
