Zusammenfassung:	According to an embodiment, disclosed are a hierarchical codebook-based channel estimation device for a multiple input/output system and a method thereof. The channel estimation device comprises: a storage unit that stores a pre-generated hierarchical codebook; and an estimation unit that estimates channel information based on transmitted pilot signals and received pilot signals, detects an optimal beamforming vector to be applied by a transceiver among beamforming vectors included in the stored hierarchical codebook by using the estimated channel information, and estimates an angle for a channel according to the detected optimal beamforming vector. 실시예에 의한 다중 입출력 시스템을 위한 계층적 코드북 기반의 채널 추정 장치 및 그 방법이 개시된다. 상기 채널 추정 장치는 미리 생성된 계층적 코드북(hierarchical codebook)을 저장하는 저장부; 및 송신 파일럿 신호들과 수신 파일럿 신호들을 기초로 채널 정보를 추정하고, 상기 추정한 채널 정보를 이용하여 상기 저장된 계층적 코드북에 포함된 빔포밍 벡터들 중 송수신기에서 적용할 최적의 빔포밍 벡터를 검출하고, 상기 검출된 최적의 빔포밍 벡터에 따른 채널에 대한 각도를 추정하는 추정부를 포함한다.
