PURPOSE: A method and device for determining whether to repeat a signal demodulation procedure are provided to determine whether to repeat a signal demodulation procedure in a receiver using a CRC(Cyclic Redundacy Check) result value. CONSTITUTION: An MIMO detector(110) outputs a soft decision log-likelihood ratio value. A first adder(120) outputs a first soft decision log-likelihood ratio value. A deinterleaver(130) deinterleaves the soft decision log-likelihood ratio value. A decoder(140) simultaneously outputs a soft decision value and a hard decision value. A first CRC checking unit(150) checks FEC CRC(Forward Error Correction Cyclical Redundancy Check). A burst assembly unit(160) outputs a received signal of a burst unit. A second CRC checking unit(170) checks the successful CRC of a data burst. An interleaver(180) interleaves a third soft decision log-likelihood ratio value outputted from a second adder(125). |
