Abstract

Codebook-based opportunistic beamforming (COBF) technique provides a beam selection diversity to the conventional opportunistic beamforming. In this paper, we design the random matrix and codebook for the COBF technique based on a kappa-factor channel model. Applying the proposed design to the COBF, nearly optimal beams are generated. Therefore, the COBF shows an outstanding performance without regard to the channel correlation related to the kappa-factor.

Codebook-based opportunistic beamforming (COBF) 기법은 파일럿을 적게 사용하면서 기존의 opportunistic beamforming 기법에 빔 선택 다이버시티를 추가한다. 본 논문에서는 채널의 상관도를 고려한 kappa-factor 채널 모델에 기반을 두어 COBF 기법에서 사용되는 랜덤 행렬과 코드북을 디자인한다. 디자인한 COBF를 적용하면 최적의 빔과 유사한 빔을 생성할 수 있고, 이에 따라 채널의 상관도가 높거나 낮음에 상관없이 항상 최적의 시스템 용량을 보인다.
