Abstract: The present invention relates to a method and an apparatus for establishing a cell using system information of neighboring cells on the basis of interference environments of the neighboring cells in a wireless communication system. The method according to the present invention comprises the steps of: detecting, by a base station, cell IDs of neighboring cells by using synchronization signals transmitted from the neighboring cells; checking whether resources, to which common reference signals (CRS) transmitted from the neighboring cells are transmitted, overlap with each other, on the basis of the cell IDs; estimating channels of the neighboring cells by using the CRS s; and determining an interference environment for establishing a cell by using the result of the checking and the estimated channels.

Abstract: Provided is a power control method of a transmitter. The method may include: generating a first aggregated carrier signal by aggregating multiple carrier signals; determining whether at least one peak exceeding a preset threshold is detected among the peaks of the first aggregated carrier signal; generating, if at least one peak exceeding the preset threshold is detected, at least one cancellation signal based on the detected at least one peak; and mapping the at least one cancellation signal to reserved subcarriers. It is possible to reduce the PAPR at the side of an amplifier by applying a tone reservation technique to multicarrier signals.

Abstract: A method for estimating a frequency offset of a reception signal and, more particularly, a signal processing method which can be applied to a receiver modem in a wireless communication system, are provided. The method includes using an absolute value within a specific time area in an inverse discrete fourier transform (IDFT) output of a decorrelation signal between a reception signal and a reference signal, and enabling a highly approximate estimation of a frequency offset through only a single decorrelation test using a characteristic of a predetermined permutation of a signal.
