Abstract

PARA UN SISTEMA DIGITAL DE TRANSMISION DE INFORMACION, CON DETERMINACION POR PARTE DEL RECEPTOR DE LA RESPUESTA DE IMPULSOS DE CANAL, SE PROPONE PARA SECTORES DE SEÑALES CON INDISTINTA SECUENCIA SIMBOLICA, DESVIAR LA RESPUESTA DEL IMPULSO DE LA FUNCION DE CORRELACION CRUZADA DE LA SECUENCIA SIMBOLICA, CON EL SECTOR DE LA SEÑAL CORRESPONDIENTE DE LA SEÑAL DE RECEPCION PALPADA, POR MEDIO DE ORGANOS CORRECTORES, QUE CONTIENEN LOS VALORES ADICIONALES DE LA FUNCION DE AUTOCORRELACION DE LA SECUENCIA SIMBOLICA. UNA NOTABLE VALORACION DE LA RESPUESTA DE IMPULSOS DE CANAL SUMINISTRA UNA IDENTIFICACION ITERATIVA. PARA SECUENCIAS SIMBOLICAS CORTAS ES CONVENIENTE UN SEGUIMIENTO DE LA RESPUESTA DE IMPULSO.
