Abstract: PURPOSE: A method for estimating channel under channel environment in which interference of neighboring base station exists in a wireless communication system and a device thereof are provide to maximally enhance existing probability of reverse matrix within channel estimation result, thereby reducing interference within receiving signal. CONSTITUTION: A unit block generating unit(11) divides PUSC(Partial Usage Sub-channel) clusters into unit blocks. A pilot matrix configuration unit(12) configures pilot matrix by each unit block. A channel estimation unit(13) estimates channel through pilot subcarrier signals. A reverse matrix determining unit determines the existence of the inverse matrix of the covariance matrix related to the channel estimation result to the pilot matrices. In case of the inverse matrix does not exist, the matrix inverse determining unit indicates the configuration of the new pilot matrix to the pilot matrix configuration unit.

Abstract: 본 발명은 이동통신망에서 채널을 추정하는 방법 및 이를 수행하는 장치에 관한 것이다.
본 발명에 따르면, 직교주파수다중분할(Orthogonal Frequency Division Multiplexing: OFDM)방식을 사용하는 이동통신망에서 인접 기지국의 간섭이 존재하는 채널 환경하에 대한 채널 추정 방법에 관한 것이다. 채널 추정을 위하여 하나의 클러스터를 2개의 부-클러스터로 분리하고 OFDM 심볼 방향으로 하나 이상의 부-클러스터(Cluster) 내에 포함되어 있는 파일럿 부반송파 신호를 사용한다.
따라서, 단일 클러스터 내에 포함되어 있는 파일럿 부반송파를 사용하여 채널을 추정하는 방법에 비하여 성능을 향상시킬 수 있는 효과가 있다.

Abstract: PURPOSE: A method for estimating channel under channel environment in which interference of neighboring base station exists in a wireless communication system and a device thereof are provide to determine existence of inverse matrix about covariance matrix of pilot subcarrier matrix included in one or more PUSC(Partial Usage Sub-Channel) cluster and obtain average about channel estimate result, thereby enhancing reliability of channel estimation. CONSTITUTION: In case of reverse matrix of covariance matrix related to pilot matrix does not exist in channel estimation result, a pilot matrix configuration unit(11) configures new pilot matrix. A channel estimation unit(12) performs averaging with the pre-obtained channel estimation result about the obtained channel estimation result and the other PUSC cluster. The channel estimation unit uses the performed result as the channel estimation result. A reverse matrix decision unit(13) determines the existence of the reverse matrix within the channel estimation result.

Abstract: A method for estimating a channel in a mobile communication network and an apparatus for performing the same are provided to improve the performance in comparison with a method of estimating a channel by using a pilot subcarrier included in a single cluster. One cluster, consisting of a data subcarrier signal and a pilot signal, is transmitted from the first base station and the second base station(S100). Respective received clusters are separated into two sub-clusters(S200). Signals transmitted from the first and second base stations are constructed into a channel estimation group(S300). A channel is estimated by using the pilot subcarrier signal included in the channel estimation group(S400).
