PROBLEM TO BE SOLVED: To provide a packet receiver capable of using an error correction code having a different coding rate for each slot, when transmitting a transmission frame composed of a plurality of slots. SOLUTION: The packet receiver 6 includes: a likelihood information extraction means 61 for extracting likelihood information on bits composing a symbol from the symbol mapped on the modulation axis of carriers; an error protection means 65 for decoding the likelihood information by an error correction coding system predetermined for the slot from which the likelihood information has been extracted; and a packet rearrangement means 67 for rearranging a decoded packet for each equal-interval packet candidate position indicating a position that becomes a candidate for arranging the packet on a temporary storage means for each slot.
