Abstract: A method and an apparatus for receiving a broadcasting signal through a digital multimedia broadcasting network are provided to improve sensitivity of an OFDM receiver by removing an IFFT(Inverse Fast Fourier Transform) unit in the OFDM(Orthogonal Frequency Division Multiplexing) receiver. An apparatus for receiving a broadcasting signal through a digital multimedia broadcasting network includes a correlation value generator(44), a frame synchronization estimator(45), a gain estimator(46), and a symbol timing offset unit(47). The correlation value generator correlates a synchronization signal, which is included in a time domain reception signal, with a reference signal, and generates a correlation value in the time domain. The frame synchronization estimator compares the time domain correlation value with a reference value. The gain estimator determines a gain based on the time domain correlation value. The symbol timing offset unit detects a sample index of the correlation value with the determined gain.

Abstract: An apparatus and a method for estimating a frequency offset improve reception performance of a mobile communication system and reduce complexity of the system by estimating interval of a subcarrier up to integral number or prime number times. A first correlative value is calculated by correlating the received signal with a signal of a first block corresponding to a part of a protective section of a reference symbol included in the received signal. A second correlative value is calculated by correlating the received signal with a signal of a second block corresponding to a part of a protective section. The first correlative value is time-delayed(S540). The frequency offset is estimated by using the delayed first and second correlative values.
