Abstract

Se proporcionan métodos y aparatos para transmitir un símbolo desde una pluralidad de antenas. En un ejemplo, un método comprende transmitir simultáneamente, desde cada antena, el símbolo multiplicado por un elemento respectivo de una columna seleccionada de una matriz. El número de filas de la matriz es al menos el número de antenas, el número de columnas de la matriz es al menos 6 y la matriz comprende o es una submatriz de una matriz de Hadamard tipo Butson que incluye solo un número mínimo de elementos no reales.
