Abstract
A transmission method according to the present invention has been conceived assuming an environment where two information source nodes independently communicate with one destination node, and thus is applicable to such a simple topology. The transmission method provides an inter-node cooperation relationship which provides a sufficient advantageous effect even in an environment in which there is a difference in the power levels of the received signals that reach the address node via two routes. The transmission method is performed by a node U1 (40) and a node U2 that is located closer to the node D (60) than the node U1 (40) to transmit signals to a node D (60) which iteratively detects a log likelihood ratio between mutually corresponding pairs of bits included in the signals at constellation points. According to the transmission method, the node U1 (40) modulates the first bit sequence to generate a first signal and transmits the generated first signal, and the node U2 (50) receives the first signal, performing logical operation on the second bit sequence and the first bit sequence included in the received first signal to generate a third bit sequence, modulates the generated thi…
