Abstract

APARATO DE TRANSMISION DE DATOS CON ORDENADOR DE ERRORES Y CALCULADORA DE POSIBILIDADES MAXIMAS. UN APARATO DE TRANSMISION DE DATOS CON UNA CARACTERISTICA MEJORADA DE TASA DE ERRORES TRAS DECODIFICACION DE DECISIONES DE PROGRAMA MEJORANDO UNA ENTRADA DE DECODIFICADOR DE TAL FORMA QUE, SEGUN UNA REALIZACION, SE RECIBEN DATOS DIGITALES TALES COMO DATOS DE VOZ TRANSMITIDOS TRAS SER APLICADOS CON CODIFICACION Y MODULACION, Y UN DEMODULADOR (''6) LOS DEMODULA COMO MODO DE TRABAJO DEL MISMO. UN VALOR MEDIO CUADRADO DE ERRORES SE OBTIENE POR MEDIO DE UNA CALCULADORA (''7) EN UNA SALIDA DEL DEMODULADOR (X), Y UNA CALCULADORA DE POSIBILIDADES (18) CALCULA (1 DIFICADOR (Y).
