Abstract

La comunicaciones inalambricas son transmitidas desde por lo menos dos radioterminales a una estacion de base de co-canal sobre un enlace de regreso utilizando un alfabeto de enlace de regreso; las comunicaciones inalambricas tambien se transmiten desde una estacion de base a las por lo menos dos radioterminales sobre un enlace de envio utilizando un alfabeto de enlace de envio que tiene mas simbolos que el alfabeto de enlace de regreso; las senales de co-canal son descifradas en el receptor, aunque las radioterminales pueden utilizar un alfabeto de enlace de regreso mas pequeno, el cual puede reducir la disipacion de energia en las radioterminales.
