Dongfeng Liu · Jisuanji gongcheng · 2012
This paper researches that the source and destination are equipped with multiple antennas,the relay only has a two-hop relay system with a single antenna.Quasi-orthogonal Space-Time Block Code(OSTBC) and MRC are employed at source,and destination,respectively,to achieve spatial diversity.To reduce the implementation complexity of the relay,the fixed-gain amplify-to-forward relay protocol is used.New exact expressions for outage probability and average bit error rate are derived in Nakagami-m fading environments.Numerical comparison results between Monte Carlo simulations show the accuracy of the theoretical expressions.
