Abstract

método e arranjo para controle de polarização em um sistema de comunicação. a presente invenção refere-se ao controle de estado de polarização de sinais a serem transmitidos de um nó de estação radiobase de capacidade mimo para uma pluralidade de equipamentos de usuário, em que o nó de estação radiobase compreende uma unidade precodificadora que conecta uma primeira e uma segunda porta de antena virtual em respectivamente uma primeira e uma segunda porta de antena de transmissão por meio das etapas de controlar (s10) uma fase relativa entre sinais de transmissão a partir de uma primeira e de uma segunda porta de antena de transmissão para proporcionar um par predeterminado de estados de polarização ortogonal para sinais transmitidos nas primeira e segunda portas de antena virtual, e intercambiar (s20) os estados de polarização da primeira e da segunda porta de antena virtual para proporcionar sinais polarizados com estados de polarização anternantes.
