Abstract

SE DESCRIBE UN METODO PARA LA DEMODULACION DE UNA SEÑAL BIFASICA CON UNA SECUENCIA DE BIT BINARIA, EN DONDE EL CAMBIO DEL VALOR DE BIT SE REPRESENTA MEDIANTE UN SALTO DE FASE DE LA OSCILACION PORTADORA. CADA UNA DE LA RELACION RELATIVA POR PARTE DEL RECEPTOR SE FORMA ENTRE EL DESARROLLO DEL ANGULO DE LA FASE QUE ENTRA DURANTE LA PRIMERA MITAD BIT Y ENTRE EL DESARROLLO DEL ANGULO DE LA FASE QUE ENTRA DURANTE LA SEGUNDA BIT. DEPENDIENDO DE ELLO, EN CUYA MITAD BIT SE DETERMINA EL ANGULO DE FASE MAYOR, SE COORDINA EL VALOR BINARIO "O" O EL VALOR BINARIO "1" A CADA UNO DE LOS BIT.
