A data reception device is provided with: a puncture rate detection element to detect the puncture rate of received data, an interpolation element to interpolate bits decimated at the detected puncture rate, a deinterleaving element to restore interleaved data to the original arrangement, and a turbo-decoding element, while variably setting the length of the learning interval according to the puncture rate detected by the puncture rate detection element, to input sliding window data and the data of the above learning interval following the data of the sliding window to the data processed by the interpolation element and deinterleaving element, and to perform recursive operations to decode the data of the sliding window. The valid received signal contained in the learning interval can be maintained approximately constant even if the puncture rate changes.
A data reception method for receiving and decoding turbo-encoded data that is encoded in units of blocks including a predetermined number of bits by a combination of convolutional encoding and interleaving and that is decimated as necessary at a predetermined puncture rate to be transmitted, comprising:
