Abstract

La presente invencion se refiere a un metodo para la representacion compacta de una senalizacion de multi-codigos que incluye determinar un numero de multi-codigos y un desplazamiento de codigo. Se formula un codigo de palabra que incluye un indicador de grupo de codigo y un indicador de desplazamiento. El codigo de palabra representa una representacion compacta de una senalizacion de multi-codigos y esta se formula y se puede decodificar sin la necesidad de una tabla de consulta.
