NJIT Assigned Patent for Frame Synchronization

Distinguished Professor Yeheskel Bar-Ness

NJIT was assigned a patent (8,126,103) developed by Miao Shi, of Kearny, and Distinguished Professor Yeheskel Bar-Ness, of Marlboro, for a "frame synchronization using correlation between permuted sequences." The abstract published by the U.S. Patent and Trademark Office states: "A permuted sequences combination uses a frame structure in which two sync words, each comprising M complex symbols, are appended at the frame start. One benefit is the reduction of the large variance of the timing estimation error in the conventional correlation method. In at least one embodiment, the first sync word, {right arrow over (s)}.sub.1, is a pre-determined constant amplitude zero autocorrelation (CAZAC) sequence. The second sync word, {right arrow over (s)}.sub.2, is a permutation of the first such that the combination of the two received sync signal vectors perform sliding window processing where the peak occurs at the correct frame start. The permuted sequences combination can be used in both AWGN channel and multi-path environments." The patent application was filed on Dec. 11, 2007 (12/001,463).
