摘要:In this paper, we investigate the ARQ technology based wireless cooperative network, which can improve the spectral efficiency and decrease the collision probability. With the application of channel estimation, the source and the relays in our scheme can decide the best terminal and the optimal cooperation protocol by their timers. Comparing to opportunistic relay selection (ORS), the spectral efficiency and collision probability could be improved. Meanwhile, comparing to Incremental Transmit Relay Selection (ITRS), the new scheme benefits from AF cooperative protocol and obtains more power gains, it is also more robust to the networks topology. Additionally, the complexity in the destination becomes lower.
