TRANSMISSION DEVICE, RECEPTION DEVICE, AND COMMUNICATION SYSTEM

WIPO Patent Application WO/2016/166822

A1

A transmission device 20 according to the present invention is provided with: a data symbol generation unit 1 that generates a data symbol; an addition unit 2 that carries out addition on at least some symbols from among past symbols, which are the data symbols of a past block; a symbol insertion unit 3 that multiplexes the post-addition past symbols with the data symbol generated by the data symbol generation unit; a DFT unit 5 that converts the symbols multiplexed by the symbol insertion unit to frequency-domain data; an IDFT unit 7 that converts the frequency-domain data to time-domain data formed from a plurality of samples; a sample selection unit 8 that selects, from the time-domain data, the sample at a selection target position, and inputs said sample to the addition unit; and a transmission unit 10 that transmits a block signal including the time-domain data. The addition unit 2 adds, to at least some symbols, an adjustment amount calculated on the basis of the sample inputted from the selection unit during the generation of the block signal of the previous block.
