Abstract—A novel concatenated code is proposed for fading channel, which combines a linear outer code with a rate-1 inner code. Based on coding and diversity technique, higher reliability can be achieved without reducing efficiency because of inner code. In the paper, the rate-1 inner code design is discussed in great detail. The design rule is shown as an optimized problem. According to different modulation and mapping style, the optimal inner coding matrixes are devised, which can be applied directly. Theoretical analysis shows that our proposed concatenated code obtains higher diversity order, which is adaptive for fading channel. Furthermore, it can be seen from the simulation result that the proposed concatenation can achieve better performance compared with the traditional concatenated code, even using the simpler outer code.
