Abstract
An adaptive distributed linear dispersion code is proposed in this article. In the first place, each relay code selects modulation type adaptively according to channel capacity. Then the candidate dispersion matrixes are selected based on the channel state weight. Finally the best transmission scheme is selected according to the system information rate and reliability. Simulation results show that the proposed adaptive coding scheme gives a more good performance.
