Nesta carta, abordamos uma estratégia para melhorar a relação sinal-interferência mais ruído (SINR) do usuário no pior caso, usando transmissão cooperativa de um conjunto de antenas geograficamente separadas. Ao contrário dos esquemas relatados anteriormente que são baseados no controle de potência de antenas individuais ou na transmissão ortogonal cooperativa, a estratégia apresentada utiliza a estrutura de filtro de erro quadrático mínimo médio (MMSE) para formação de feixe, que fornece maior robustez à interferência externa, bem como o ruído de fundo no receptor. Ao atualizar iterativamente o vetor de formação de feixe de transmissão cooperativa e o controle de potência (PC), o SINR balanceado é obtido para todos os usuários, enquanto a potência de transmissão de cada antena também converge para dentro do valor restrito. É demonstrado que a formação de feixe MMSE proposta supera significativamente outros esquemas existentes em termos do SINR mínimo alcançável.

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.
