dc.description | En este trabajo se propone una metodología de estimación de fase por subbandas de un canal de respuesta no uniforme. La novedad de la propuesta radica en la utilización de un formato de modulación en fase en cuadratura QPSK, (Quadrature Phase Shift Keying) modificado como señal de prueba para la estimación de fase que elimina el problema de la ambigüedad. La metodología propuesta se verifica experimentalmente utilizando como canal de transmisión un cable de RF defectuoso, logrando la transmisión de datos a tasas de 20 Kbaud en una distancia de 120 cm en una banda de frecuencias comprendida entre los 150 kHz y 276 kHz. | |
