Abstract
A transmission device capable of reducing packet receiving errors and the number of retransmissions by improving error correction coding gain without increasing the amount of resources used in transmission. The transmission device (100) that transmits each bit of coded data constituted from systematic bits and parity bits in order for each transmission unit, and performs frequency puncturing to puncture, in units of symbols, data to be punctured in which each bit has been superimposed on a plurality of frequency domain symbols. A time puncturing unit (102) extracts transmission unit data from the coded data and a frequency puncturing unit (105) performs frequency puncturing in accordance with the ratio of parity bits to systematic bits included in the data.
