Apparatus selectively adopting different determining criteria in erasure marking procedure when performing decoding process, and method thereof

Abstract

A method and a related apparatus that decode an input signal to generate an output signal. The method includes determining burst noise locations corresponding to the input signal and generating a first indication signal accordingly, decoding the input signal to generate an inner-code decoded signal, selectively adopting one of a plurality of determining criteria according to the first indication signal to determine reliability information corresponding to the inner-code decoded signal and to generate a second indication signal accordingly, and decoding the inner-code decoded signal with reference to the second indication signal to generate the output signal.

1 . An apparatus for decoding an input signal to generate an output signal, the apparatus comprising:
 a noise detector for determining a burst noise location corresponding to the input signal and generating a first indication signal for indicating the burst noise location;   an inner decoder for decoding the input signal to generate an inner-code decoded signal;   a reliability-determining unit coupled to the noise detector, for selectively adopting one of a plurality of determining criteria according to the first indication signal to determine reliability information corresponding to the inner-code decoded signal and to generate a second indication signal; and   an outer decoder coupled to the inner decoder and the reliability-determining unit, the outer decoder decoding the inner-code decoded signal with reference to the second indication signal to generate the output signal.   
   
   
       2 . A method for decoding an input signal to generate an output signal, the method comprising:
 determining a burst noise location corresponding to the input signal and generating a first indication signal indicating the burst noise location;   decoding the input signal to generate an inner-code decoded signal;   selectively adopting one of a plurality of determining criteria according to the first indication signal to determine reliability information corresponding to the inner-code decoded signal and to generate a second indication signal; and   decoding the inner-code decoded signal with reference to the second indication signal to generate the output signal.
