Abstract:
1. 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: processing received data to judge the puncture rate; interpolation processing to interpolate decimated bits at said puncture rate; deinterleave processing to restore said interleaved data to an original arrangement; and turbo-decoding processing of data subjected to said interpolation processing and to said deinterleave processing, in which, while variably setting the length of a learning interval according to the judged puncture rate, the data of a sliding window and the data of said learning interval following the data of the sliding window are input to decode the data of the sliding window by recursive operations.
