Abstract
RECEPTOR Y METODO DE RECEPCION DE DATOS TRANSMITIDOS EN UN SISTEMA DE COMUNICACIONES POR RADIO EN EL MODO DE RAFAGA. UN METODO PARA RECIBIR DATOS TRANSMITIDOS EN UN SISTEMA DE COMUNICACIONES POR RADIO EN EL MODO DE RAFAGA, TAL COMO GSM. ANTES DE LA TRANSMISION, UN CONJUNTO DE PRIMEROS ELEMENTOS DE DATOS (BITS), QUE SE REFIEREN A UN PRIMER MENSAJE QUE SE PUEDE ASOCIAR CON UN PRIMER TIPO DE CANAL (POR EJEMPLO, UN CANAL DE TRAFICO (TCH) EN GSM), HA SELECCIONADO BITS SUBSTITUIDOS O "ROBADOS" POR ELEMENTOS DE DATOS (BITS), QUE SE REFIEREN A UN SEGUNDO MENSAJE QUE SE PUEDE ASOCIAR CON UN SEGUNDO TIPO DE CANAL (POR EJEMPLO, UN CANAL ASOCIADO RAPIDO FACCH EN GSM). LOS ELEMENTOS DE DATOS QUE SE REFIEREN AL PRIMERO Y AL SEGUNDO MENSAJE SE INTERPOLAN SOBRE EL MISMO NUMERO O SOBRE UN NUMERO DIFERENTE DE RAFAGAS. EN UNA RAFAGA DE TRAFICO GSM NORMAL, DOS INDICADORES DE UN SOLO BIT SE FIJAN EN "1" PARA INDICAR CUANDO LOS BITS DE PARIDAD PAR O LOS BITS DE PARIDAD IMPAR DE LA RAFAGA HAN SIDO ROBADOS PARA DATOS FACCH. SE EMPLEA UN DETECTOR (5) PARA SUPERVISAR LOS INDICADORES DEL MISMO NUMERO DE RAFAGAS SOBRE LOS QUE SE INTERPOLA EL FACCH. PARA MEJORAR LA POSIBILIDAD DE DETECCION DE UN FACCH EN CONDICIONES RUIDOSAS, SE EMPLEA UN CIRCUITO DE VOTO DE MAYORIA (9), EN EL QUE SE INICIA UNA DECODIFICACION FACCH SI EL NUMERO DE INDICADORES DETECTADOS FIJADOS EN "1" EXCEDE UN VALOR UMBRAL. ESPECIFICAMENTE, EN EL CASO DE FACCH, EL VALOR UMBRAL PUEDE SER 5-8, ES DECIR, MAS DE LA MITAD DEL NUMERO DE RAFAGAS SOBRE LAS QUE SE INTERPOLAN LOS DATOS FACCH.
