Performance Analysis of a Dual-Hop Relay With STBC-CIOD over Rayleigh Fading Channels
Jungho Myung, Hoojin Lee, Joonhyuk Kang · IEEE Transactions on Vehicular Technology · 2012
In this paper, a symbol error rate (SER) study is presented for the dual-hop relay networks employing space-time block code (STBC) from coordinate interleaved orthogonal design (STBC-CIOD), where a relay with either a decode-and-forward (DF) or an amplify-and-forward (AF) protocol is equipped with multiple antennas. More specifically, we provide the union upper and lower bounds on the average SER by deriving an accurate closed-form formula for the corresponding symbol pairwise error rate (SPER). In addition, the asymptotic diversity order is analyzed. The theoretically derived bounds are in good agreement with the simulation results.
