Superposition Modulated Cooperative Diversity for Half-duplex Scenario
Full Text: PDF (413 KB)
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. 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.
