Diversity-and-Multiplexing Tradeoff of Superposition Coding Relaying Strategy without Channel State Feedback
Laiqiang Zhao, Haiyang Fu, Xiangdong Jia · 2010
Superposition coding relaying (SC-relaying) has the merit of high throughput. At the same time, the investigation of the diversity-multiplexing tradeoff (DMT) is also particularly useful for the design and analysis of cooperative relaying strategy. In this work, we consider a two-level rate SC-relaying strategy without the channel state feedback under short term power constraint. For the SC-relaying strategy, the optimizing DMT is investigated as well as its optimizing close-form explicit solution.
