On the Performance Analysis of Distributed Space-Time Code over Nakagami-m Multipath Channels
Zhirong Zhong, S. ZHU, Gangming Lv · IEICE Transactions on Communications · 2008
In this letter, we analyze the pairwise error probability (PEP) behaviour of distributed space-time code (DSTC) with amplify-and-forward relaying over Nakagami-m multipath channels. An upper bound of PEP for DSTC is derived. From our analysis, it is seen that of the paths from the source to relays and from relays to the destination, those with smaller diversity order result in an overall system performance bottleneck. Numerical examples are provided to corroborate our theoretical analysis.
