Abstract :
We propose co-efficient vector based differential distributed quasi-orthogonal space time block codes (DQSTBC) for cooperative networks utilizing the decode-and-forward protocol. In our work, we employ rotated constellation quasiorthogonal codes which guarantee full code-rate and full diversity in cooperative networks with more than two relay nodes.
