    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: According to an embodiment of the present invention, a method for combining reception signals of a reception device in a wireless communication system comprises the steps of: determining N (here, N is a natural number) number of symbols for performing symbol combining with respect to reception signals; symbol-combining the reception signals for L (here, L is a natural number) number of times according to the determination result; and energy-combining each group of the L number of reception signals for which the symbol combining has been performed. The present research has been performed by receiving support from “Giga KOREA project” of the Ministry of Science, ICT, and Future Planning.

    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.
