Abstract

The present invention relates to an early stopping system and method for a low power consumption turbo decoder, which compares soft-decided output values of information bits output by component decoders of the turbo decoder to determine whether or not an iterative decoding process of the turbo decoder is finished, and stops the iterative decoding process early if it is determined that the iterative decoding process is not needed anymore since the decoding of information bits is finished, to thereby reduce an average count of iterative decoding processes of the turbo decoder and to thus reduce power consumption and improve bit error rate (BER).
