Abstract: An apparatus and method for recovering a carrier frequency of a received signal using a predefined symbol in an OFDM system is provided. A maximum value detector detects at least three values and their corresponding offsets in descending order among auto-correlation values calculated within a specific frequency offset range between a received signal and a predefined symbol. A frequency offset corrector compares a ratio of a first auto-correlation value to a second auto-correlation value with a predetermined first threshold, determines whether first and second frequency offsets corresponding to the first and second auto-correlation values are adjacent to each other if the ratio of the auto-correlation values is less than the first threshold, and determines an initial carrier frequency offset using a difference between the first frequency offset and a frequency offset correction value determined according to system, if the first and second frequency offsets are adjacent to each other and a ratio of the second auto-correlation value and a third auto-correlation value is greater than a predetermined second threshold.

Abstract: An apparatus and method for carrier frequency synchronization in an Orthogonal Frequency Division Multiplexing (OFDM) system are provided for correcting an initial carrier frequency offset in the OFDM system. A metric generator for frequency estimation performs a first accumulation process for a value computed by multiplying a Phase Reference Symbol (PRS) generated from a reception stage by a Fast Fourier Transform (FFT) output signal for an OFDM symbol in a PRS position within a frame, acquires a differential symbol from a product of adjacent FFT output symbols, performs a second accumulation process for a real part extracted from the differential symbol, and outputs a metric value for the frequency estimation. A maximal value-related index generator compares metric values for initial frequency estimation within a predetermined frequency offset estimation range, and selects and outputs a maximal metric value as a frequency offset estimate.

Abstract: A method for manufacturing an electrode may include (S1) preparing a sol solution containing a metal alkoxide compound, and (S2) forming a porous non-woven coating layer of an inorganic fiber by electroemitting the sol solution onto an outer surface of an electrode active material layer formed on at least one surface of a current collector. The porous non-woven coating layer formed on the outer surface of the electrode active material layer may be made from an inorganic fiber having excellent thermal stability. When an electrochemical device is overheated, the porous non-woven coating layer may contribute to suppression of a short circuit between a cathode and an anode and performance improvement of an electrochemical device due to uniform distribution of pores.
