Embodiment Construction
[0231] Specific embodiments of the present invention are given below, and the present invention is further described in conjunction with the accompanying drawings.
[0232] The purpose of the present invention is to propose a practical adaptive coding relay system and method for uplink multiple access relay access channel scenarios, so as to fully utilize the advantages of different methods in different scenarios and optimize system performance. Traditional hard-decision network coding schemes require completely correct reception of source information, thus requiring high relay link quality; while relay schemes based on soft bit information can only achieve relatively better results under low relay link quality environments. performance. There is no one method that can adapt to various scenarios and obtain excellent performance in various environments. Therefore, self-adaptation is particularly important and feasible in practical systems.
