Abstract
Provided is a cooperative multimedia communication system. The source node includes a first hierarchical modulation constellation diagram, modulates two data streams and transmits a first signal and a second signal. The relay node includes a protection-level-exchanging modulation and a second hierarchical modulation constellation diagram, modulates the second signal to generate a third signal and transmits the third signal. The destination node receives the first signal and the third signal and performs optimal decoding. The present disclosure designs a pair of optimal hierarchical constellation diagrams respectively for the source node and the relay node. Moreover, the present disclosure further provides a cooperative multimedia communication method.
