Cooperative Transmit Diversity Utilizing Superposition Modulation
Koji Ishii · 2007
In this paper, the cooperative diversity with superposition modulation, which has been proposed as an instance of "dirty paper coding", is theoretically analyzed using the outage probability. We investigate the relationship between outage probability and transmission-rate corresponding to the parameter of superposition modulation. Moreover, we extend the modulation of this cooperative transmission system from one to two-dimensions and provide the system optimization
