Abstract:
1. A communication method using a random linear code, the communication method comprising: receiving from a transmitter, first code blocks randomly linear-coded by the transmitter; demodulating the first code blocks by the transmitter using a decision distance determined in accordance with a channel status; determining whether an error has occurred in the first code blocks using the decision distance; transmitting a non-acknowledgement (NACK) signal to the transmitter when the error has occurred, wherein the NACK signal includes information of a number of code blocks where the error has occurred among the first code blocks; and receiving from the transmitter, second code blocks, as many as the number of code blocks where the error has occurred among the first code blocks, randomly linear-coded by the transmitter, wherein the second code blocks are generated by using different random coefficients from random coefficients used for the first code blocks.
