이 편지에서는 지리적으로 분리된 안테나 세트의 협력 전송을 사용하여 최악의 사용자의 신호 대 간섭 및 잡음 비율(SINR)을 향상시키는 전략을 다룹니다. 개별 안테나의 전력 제어 또는 협력적 직교 전송을 기반으로 하는 이전에 보고된 방식과 달리 제시된 전략은 빔 형성을 위해 MMSE(최소 평균 제곱 오차) 필터 구조를 활용합니다. 수신기의 배경 소음. 협력 전송 빔포밍 벡터와 전력 제어(PC)를 반복적으로 업데이트함으로써 모든 사용자에 대해 균형 잡힌 SINR을 얻고, 각 안테나의 전송 전력도 제한된 값 내로 수렴됩니다. 제안된 MMSE 빔포밍은 달성 가능한 최소 SINR 측면에서 다른 기존 방식보다 훨씬 뛰어난 성능을 보인다는 것이 입증되었습니다.

Abstract: In this letter, we address a strategy to enhance the signal-to-interference plus noise ratio (SINR) of the worst-case user by using cooperative transmission from a set of geographically separated antennas. Unlike previously reported schemes which are based on either the power control of individual antennas or cooperative orthogonal transmission, the presented strategy utilizes the minimum-mean-squared error (MMSE) filter structure for beamforming, which provides increased robustness to the external interference as well as the background noise at the receiver. By iteratively updating the cooperative transmission beamforming vector and power control (PC), the balanced SINR is obtained for all users, while the transmission power from each antenna also converges to within the constrained value. It is demonstrated that proposed MMSE beamforming significantly outperforms other existing schemes in terms of the achievable minimum SINR.
