Abstract
UN RECEPTOR PARA UNA SEÑAL PSK INCLUYE UN DEMODULADOR (DEM) PARA OBTENER UNA SEÑAL DE DATO DEMODULADA QUE DESPUES DE LA REGENERACION EN ELEMENTOS DE REGENERACION (HL, DR, TU) ES APLICADA A UN REMODULADOR (REM) PARA REMODULACION - PSK DE LA SEÑAL - PSK RECIBIDA PARA PRODUCIR POR ELLO UN COMPONENTE PORTADOR QUE SE APLICA COMO UNA SEÑAL DE ENTRADA A UN CIRCUITO CERRADO SINCRONIZADO (PLL) EN EL CUAL UN GENERADOR PORTADOR LOCAL (VCO1) SE INCLUYE. LA FIABILIDAD DE LA PORTADORA RECUPERADO POR BAJO DE VALORES SNR PUEDE SER MEJORADA POR REALIZAR LOS ELEMENTOS DE REGENERACION (DR, TU) TAMBIEN POR LA GENERACION DE VERSIONES RETRASADA (AL) Y AVANZADA (AE) DE LA SEÑAL DE DATOS REGENERADA (AR), Y POR PROVEER EL RECEPTOR EN ADICION CON ELEMENTOS (CTU), SENSIBLE A LA SEÑAL - PSK RECIBIDA, LA PORTADORA LOCAL Y LAS VERSIONES DE SEÑAL DE DATOS SETRASADA Y AVANZADA (AL, AE), PARA GENERAR UNA SEÑAL DE CONTROL (RL - RE) POR UN GENERADOR CONTADOR LOCAL (VCO2) CONECTADO A LOS ELEMENTOS DE REGENERACION (TU, DR).
