Abstract: An iterative detection and decoding (IDD) device in a receiving device of a wireless communication system by using multiple-input multiple-output (MIMO) and a channel code by connecting is provided. The IDD device includes an MIMO detector that generates an output log likelihood ratio (LLR) value by using signals received from a plurality of antennas and a feedback LLR value, a channel decoder for outputting a channel decoded LLR value through channel decoding and a second operation by using the LLR value of the MIMO detector, and a feedback compensator for generating the feedback LLR value so that the channel decoded LLR value is within the range of an upper threshold and a lower threshold determined based on a bit width of an LLR used by the receiving device.

Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate than a 4G communication system such as LTE. The method is for phase correction of an antenna in a large-capacity antenna system, the method includes grouping large-capacity antennas into a predetermined number of groups; setting a path such that ports of the grouped antennas have a feedback path; outputting a test signal to be outputted to each antenna port of each group by adding a code or sequence having orthogonality; separating signals for each antenna port in the group by using the code or sequence having orthogonality in a signal received through the feedback path; and calculating a calibration value by detecting a phase change of the separated signal.

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: 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 CRSs; and determining an interference environment for establishing a cell by using the result of the checking and the estimated channels.
