Abstract

La invencion se refiere a un metodo y aparato para implementar la fase de entrenamiento de igualacion de canal adaptable en una trayectoria de comunicaciones digitales haciendo pasar senales moduladas utilizando QAM o CAP en una configuracion de sistema, en donde el transmisor o el receptor, o ambos, incluyen filtros eliminadores de banda que forman por lo menos una banda de detencion sobre el espectro de senal. En el metodo, e entrenamiento de los igualadores adaptables se realiza utilizando una constelacion de simbolo escasa, en donde el numero de estados de simbolo (S) se reduce de aquel de la constelacion de simbolo utilizada en el estado normal de transmision de datos. El beneficio de la constelacion de simbolo escasa es que la interfase entre simbolos fuerte causada por una banda de detencion que cae sobre el espectro de senal puede ser asi reducida a un bajo nivel con respecto a la energia de senal que un igualador lineal puede ser usado para llegar a una situacion, en donde la proporcion de decisiones de recuperacion de simbolo correctas se vuelve suficientemente alta para el entrenamiento de un igualador de decision-realimentacion.
