Abstract

método e aparelho para retroinformar e construir uma matriz de correlação em sistemas de múltiplas entradas e múltiplas saídas. a presente invenção refere-se a um método para retroinformar uma matriz de de correlação em um sistema de múltiplas entradas e múltiplas saídas, que compreende: construir livros-código para a matriz de correlação com base em uma natureza de conjugação da matriz de correlação e com base em uma relação predeterminada entre os elementos da diagonal e os elementos fora da diagonal na matriz de correlação; selecionar uma palavra-código a partir do livro-código construído; e retroinformar um indíce correspondente da palavra-código selecionada no livro-código. através da presente invenção, pode-se aprimorar o rendimento do sistema de múltiplas entradas e múltiplas saídas, enquanto se reduz a complexidade do codificador ou de carga de transferência.
