Summary: | This paper proposes a non-orthogonal multiple access system based on rateless codes to improve anti-jamming performance. Firstly, each user's data is encoded by rateless codes. Then all the data is superimposed to form some composite signals, which are broadcast to every user. The power factors of each user and the superimposed signals are adjusted by the transmitter according to feedback provided by the users. This paper also analyzes the packet loss ratio, the frame error rate (FER) and the decoding time. The simulation results show that the proposed scheme not only reduces the FER, but also improves the system throughput. |
