| Abstract: | According to the good properties and characteristics of LDLC, This paper studies cooperative diversity system and presents a scheme of LDLC applied in the case of two users to collaborate, the terminal uses the multiplying the normalized way. The results show that: the performance of LDLC under the cooperative system performance is better than that of no coding, and cooperation performance is relatd with channel condition, which strategy to use depends on CSI. |
