Abstract: PURPOSE: An indoor positioning system and a method thereof are provided to accurately estimate a distance between nodes by minimizing an error rate using delay time estimation. CONSTITUTION: A transmission node(100) generates and transmits a transmission packet including multiple identical symbols. A receiving node(200) receives a transmission packet transmitted from a transmission node and estimates a delay time by using a matrix pencil algorithm and symbols included in the received transmission packet.

Abstract: PURPOSE: An implementation method of an efficient voice/music classifier proper to marine environment is provided to obtain input vectors from a cache memory of the classifier and to convert a source code of the classifier, thereby shortening execution time and saving energy consumption. CONSTITUTION: An input vector is obtained from a cache memory of a classifier. A source code of the classifier is converted. The source code of the classifier is converted by adding an intermediate value storage variable and the last classification value storage variable for processing input vectors at the same time. [Reference numerals] (a) Address of a support vector; (b) Content of a cache block 0 and a register n

Abstract: PURPOSE: A signal extracting device is provided to improve a CNR(Carrier-to Noise Ratio) by generating PRZ(Pseudo Return-to-Zero). CONSTITUTION: A clock extracting unit extracts a clock from an NRZ signal. Interval lattice is regularly arranged in parallel. A generating unit generates a clock signal by using an optical fiber ring laser which is locked with the interval lattice. The interval lattice is constructed as a cladding mode and a core mode. The interval lattice is used as an NRZ-to-PRZ converter.
