    Abstract: DECODIFICADOR Y METODO PARA EL MISMO, DONDE UN DECODIFICADOR (223) INCLUYE UN CIRCUITO DE PROBABILIDAD (432) QUE GENERA METRICAS DE RAMA USANDO PROBABILIDADES DE BIT QUE REPRESENTAN LAS RELACIONES DE CORRELACION TRAMA A TRAMA. LAS METRICAS DE RAMA SE INTRODUCEN EN UN DECODIFICADOR (434) QUE ENTREGA BITS DE DATOS DECODIFICADOS EN FUNCION DE LAS PROBABILIDADES DE BIT PARA, AL MENOS, PREDETERMINADAS POSICIONES DE LOS BITS.

    Abstract: A receiver for decoding a differentially-encoded communication signal transmitted thereto over a communication channel comprises means 1390, 1420 for demodulating the differentially-encoded communication signal, sampling units 1398, 1428 for sampling at least portions of the demodulated received signal, and a decoding metric estimator 1450 coupled to receive the sampled signal. The decoding metric estimator includes a delay element 1266, a complex conjugate converter 1270 and a mixer 1274 operative to mix the sampled signal and the complex conjugate signal to form a metric estimation signal. A soft decision decoder 1470 receives and decodes the metric estimation signal. A symbol detector (1226, Fig. 9) may be connected between the delay element and the complex conjugate converter. The symbol detector may comprise a magnitude setter (1220) and a phase quantizer (1224).
