PROBLEM TO BE SOLVED: To provide a turbo decoder, which reduces power consumption. SOLUTION: Concerning a turbo decoder 1 for performing turbo decoding by inputting turbo-encoded data for the unit of a block, while referring to a look-up table 20, the number of times of repetition, corresponding to an estimated signal/noise ratio, is estimated by a root mean circuit 19 and decremented by a counter part 21, so that turbo decoding is performed for that number of times of repetition.
