The Upper and Lower Bound of Distributed Cooperative Communication

In order to study the impact of node mobility upon distributed cooperative communication, a three-node model was established. It used Alamouti coding. Using bit error rate as a metric, the cooperative communication parameter was defined. Compared with Alamouti2times1 and direct communication separately, cooperative communication achieved its upper and lower bound. The simulation results show that under the circumstance of S-R channelpsilas good performance, as long as S-D and R-D channel satisfy certain conditions, the cooperative communication will be superior to Alamouti2times1 and direct communication.
