Abstract

Se revela un sistema para transmitir mensajes de datos digitales entre una pluralidad de estaciones que utilizan un canal común de comunicaciones.Los mensajes de datos se reunen en paquetes de datos que incluyen información dedireccionamiento y de control. Se transmiten entonces los paquetes desdelas estaciones y a través del canal común utilizando formas de ondas representativas de los datos o modulación. Se recibe una forma de ondacompuesta representativa delos paquetes de datos que incluye potencialmente paquetes de datos que se superponen en el tiempo y se la procesa paradecodificar por lo menos un paquete. La forma de onda representativa de paquete, presente por lo menos en cantidad deuno, se reconstruye y se eliminade la forma de onda compuesta recibida por sustracción a fin de obtener una forma de onda residual. Se somete la forma de onda residual a un procesoulterior para intentar decodificar por lo menos otro paquete.
