Abstract :
In the above mentioned paper, the authors proposed an incremental transmission relay selection (ITRS) protocol, whose diversity-multiplexing-tradeoff performance was illustrated and compared with existing alternatives in Fig. 3 (R. Tannious et al., Oct, 2008). However, in our opinion, these comparisons are unfair and a curve depicted in Fig. 3 is wrong. We discuss the full detail of our comment in this paper.
