Abstract :
Cooperative communication uses multipath transmission to combat the effect of individual severe fading and path loss. So far, there are mainly three types of cooperative schemes: Amplify-and-Forward, Decode-and-Forward, and Coded Cooperation. This paper presents a convolutional coded system model and performance comparison between these three schemes. Also, this paper reveals two important parameters that determine the performance of different levels of Coded Cooperation schemes: percentage of cooperation and distributed effect for the transmitted symbols. They will be analysed and some contributing conclusions of our work will be drawn.
