Superposition Modulated Cooperative Diversity for Half-duplex Scenario
Koji Ishii · Journal of Communications · 2007
Abstract—In this paper, the cooperative diversity with super-position modulation, which has been proposed as an instance of “dirty paper coding”, is theoretically analyzed using the outage probability. However, the conventional system with superposition modulation cannot ideally perform dirty paper coding. Thus, we propose to apply constellation rotation technique and iterative processing to the superposition modulated system, which yields a performance close to the ideal one. Index Terms—cooperative diversity, dirty paper coding, superposition modulation, constellation rotation, iterative processing I.
