Abstract

Un precodificador (112) para un sistema de comunicacion organizado para suministrar bloques de transmision (t(i)) para la transmision sobre un canal de transmision (120) basado sobre bloques de símbolos ingresados (x(i)). El precodificador está organizado para predistorsionar cada bloque de símbolos (x(i)) basado sobre el cálculo de las características del canal de transmision de modo tal que el bloque de transmision correspondiente (t(i)) parece no estar distorcionado después de la transmision sobre el canal de transmision. De acuerdo con eso, el precodificador está organizado para aplicar la precodificacion Tomlinson-Harashima sobre una suma de una primera medida correspondiente a la predistorsion a fin de eliminar la interferencia dentro de símbolos y una segunda medida correspondiente a la predistorsion a fin de eliminar la interferencia entre símbolos. Se relaciona además con un método para suministrar bloques de transmision (t(i)) para la transmision sobre un canal de transmision (120) en un sistema de comunicacion.
