Abstract

resumo método de feedback indicador de matriz de pré-codificação, receptor final, e transmissão final a presente invenção proporciona um método de matriz pré-codificação realimentação indicador, uma extremidade receber, e um terminal de transmissão. o método inclui: selecionar, por uma extremidade receber com base em um sinal de referência, uma matriz pré-codificação w a partir de um livro de códigos, em que um coeficiente é utilizado para executar o ajuste de fase em no w, o representa uma diferença de fase entre os valores ponderados de uma primeira antena grupo e um segundo grupo de antena de um terminal de transmissão de um sinal de transmissão a partir de uma mesma camada de transmissão, o , o n é um número inteiro não negativo, o símbolo q representa um número inteiro positivo, e o primeiro grupo de antenas e o segundo grupo de antenas pertencem um mesmo sistema multi-antena; e o envio, pela extremidade receber, um indicador da matriz de pré-codificação pmi para o terminal de transmissão, de modo que o terminal de transmissão determina a w de acordo com o pmi. deste modo, utilizando o coeficiente para realizar o ajuste de fase no pode aumentar o tamanho de um livro de códigos definido aplicável a diferentes configurações de antena, e melhorar a precisão da extremidade de recepção para realimentar um pmi.
