Abstract—In this paper, the cooperative diversity with superpositionmodulation, which has been proposed as an instanceof “dirty paper coding”, is theoretically analyzed using theoutage probability. However, the conventional system withsuperposition modulation cannot ideally perform dirty papercoding. Thus, we propose to apply constellation rotationtechnique and iterative processing to the superpositionmodulated system, which yields a performance close to theideal one.
