Mutual information forwarding scheme based on MPSK modulation
摘要
Abstract
In order to ensure the validity and reliability of information transmission,the cooperated forward scheme is ana-lyzed,and a scheme of mutual information forwarding executed after multi-system modulation is proposed based on Rayleigh fading channel,which is compared with amplify forwarding scheme,detect forwarding scheme and estimate forwarding scheme in bit the error rate performance. The simulation results show that the mutual information forwarding scheme based on MPSK modula-tion is always superior to the other schemes. When the signal-to-noise ratio is the same,with the increasing of the modulation or-der,the date rate increased,and the reliability of each scheme is reduced obviously. When the higher transmission rate is need,somereliability can be sacrificed to exchange for the validity of the transmission.关键词
