Abstract

Técnicas para soportar MC-CDMA (Multi Carrier-Code Division Multiple Acces, Acceso Multiple por Division de Codigo de Multiples Portadores) en un enlace ascendente ortogonal de un sistema de comunicaciones inalámbrico. Un método de comunicaciones inalámbricas de multiples portadores comprende dividir subportadores sobre un enlace ascendente en grupos no superpuesto, atribuir un bloque de tiempo-frecuencia que incluye una duracion de salto y un grupo no superpuesto, respectivamente, asignar un conjunto diferente de codigos ortogonales a cada usuario, distribuir símbolos de datos ( o de pilotos) de cada usuario por medio del boque de tiempo-frecuencia atribuido, en el que los símbolos del dato ( o de pilotos) de cada usuario se distribuyen utilizando el conjunto diferente codigos ortogonales asignados a cada usuario, mapear cada símbolo de datos ( o de pilotos) a un símbolo de modulacion en el bloque de tiempo-frecuencia, generar una onda ortogonal basada en los símbolos mapeados, y transmitir la onda ortogonal.
