Abstract
En una conexion TDMA de movil a movil, la calidad de la señal de audio de extremo a extremo así como el desempeño del sistema puede mejorarse proporcionando a procesadores de señal digital la capacidad de conmutar automáticamente la configuracion, de tal forma que cada procesador de señal digital en una conexion de comunicacion de movil puede identificar automáticamente una conexion TDMA de movil a movil y derivar los procesos de codificacion y decodificacion de voz dentro de los procesadores de señal digital. Los dos procesadores de señal digital están conectados en forma virtual en los codecs de canal.
