摘要
研究固定增益放大转发协议,信源和终端需要配置多根天线,而中继只有单根天线的两跳中继转发系统。为获得空间分集,信源利用正交空时分组编码的发射策略,终端利用选择合并方式,简化中继配置的复杂度,采用固定增益放大转发的协议。导出Nakagami-m衰落下系统终端概率的封闭表达式与平均误比特率的封闭表达式,通过蒙特卡罗仿真和数值结果比较,验证了封闭表达式的精确性。
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-folward 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.
