Abstract:
1. A transmission method performed by a first transmission device and a second transmission device to transmit signals to a reception device which iteratively detects a log likelihood ratio in units of a pair of bits included in the respective signals at constellation points, the second transmission device being located closer to the reception device than the first transmission device, and said transmission method comprising: generating a first signal by modulating a first bit sequence, and transmitting the generated first signal to the second transmission device and the reception device, said generating and transmitting being performed by the first transmission device; receiving the first signal, and extracting the first bit sequence included in the received first signal, said receiving and extracting being performed by the second transmission device; generating a third bit sequence by performing, in units of a pair of bits, logical operation on the first bit sequence extracted in said receiving and extracting and a second bit sequence, said generating being performed by the second transmission device; and generating a second signal by modulating the third bit sequence, and transmitting the generated second signal to the reception device, said generating and transmitting being performed by the second transmission device.
