Method and apparatus of communication using random linear coding

摘要

A communication method using random linear coding is disclosed. The communication method using a random linear code comprises receiving first code blocks randomly linear-coded from a transmitter; demodulating the first code blocks 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, and transmitting a NACK signal to the transmitter, the NACK signal including information of the number of the code blocks where an error has occurred. Since a block error rate can be controlled in accordance with channel status, throughput can be improved.

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.
