In this paper a physical layer transmission method based on the channel prediction and users quality-of-service(QoS) is proposed. The time-varying Rayleigh fading channel is predicted by back propagation neural network (BPNN), which will serve as judging whether the system secure transmission capacity is redundant. Then a scheme to choose the best physical layer security coding under the secure transmission capacity satisfies the users QoS is introduced.
