| 抄録: | This paper proposes a simple coding structure withiterative spatial demapper (ISM) for single carrier transmission of two correlated sources (with instantaneous power control) over fading multiple access channel (Fading MAC) where the receiver has only a single receive antenna. The correlation between the sources is exploited via vertical iteration (VI) loop between the two decoders and analyzed based on the Slepian-Wolf (SW) coding theorem. The proposed structure, of which potential applications are sensor or relay systems requiring relatively small number of the transmission phases, can achieve turbolikeperformance over Fading MAC even with short memoryconvolutional codes (CC). The rate-1 doped accumulator (DACC) is used to flexibly adapt the variation of the correlation between the sources which makes the convergence tunnel between the demapper and decoder open until a point very close to (1,1) mutual information (MI) point. The results of computer simulations confirm that the proposed structure can achieve close performance to the Slepian-Wolf/Shannon limit of two correlated sources using single transmission phase. |
