Abstract

Se proporcionan métodos y aparatos para transmitir un símbolo de una pluralidad de antenas. En un ejemplo, un método comprende transmitir simultáneamente, desde cada antena, el símbolo multiplicado por un respectivo elemento de una columna seleccionada de una matriz. El número de hileras de la matriz es al menos el número de antenas, el número de columnas de la matriz es al menos 9, y la matriz comprende o es una submatriz de una matriz de Hadamard real de exceso máximo.
