Abstract
Un método para realizar una precodificación basándose en un desplazamiento de fase generalizado o una precodificación basándose en un desplazamiento de fase extendido en un sistema de Múltiple-Entrada, Múltiple-Salida (MIMO) que emplea varias subportadoras, y un transceptor para soportar lo mismo se describen. Una matriz de precodificación basada en desplazamiento de fase se generaliza al multiplicar una matriz diagonal para un desplazamiento de fase por una matriz unitaria para mantener la capacidad ortogonal entre subportadoras. En este caso, una parte de la matriz diagonal puede extenderse al multiplicar una matriz de precodificación para remover la interferencia entre subportadoras por una matriz diagonal para un desplazamiento de fase. Por generalización y extensión la precodificación basada en desplazamiento de fase, un transceptor es más simplificado y la eficiencia de comunicación incrementa.
