PROBLEM TO BE SOLVED: To provide a packet reception device capable of using an error correction code different in code rate for each slot when a transmission frame composed of a plurality of slots is transmitted. SOLUTION: The packet reception device 6 includes a likelihood information extracting means 61 of extracting likelihood information on bits constituting a symbol from the symbol mapped on a modulation axis of a carrier, an error protecting means 65 of decoding the likelihood information by an error correction code system predetermined for the slot where the likelihood information is extracted, and a packet rearranging means 67 of rearranging a decoded packet at each of equal-interval packet candidate positions indicating positions as candidates where decoded packets in a temporary storage means are to be arranged for the slots.
