| 摘 要： | 研究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。为了获得空间分集,信源利用了正交空时分组编码（OSTBC）的发射策略,终端利用了选择合并方式。为了尽可能简化中继配置的复杂度,中继采用固定增益放大转发的协议。在信源和终端直接通信链路存在的情形下,首先导出总的接收信噪比的表达式,接着导出瑞利衰落条件下系统中断概率的封闭表达式,最后通过蒙特卡洛仿真和数值结果的比较,验证了理论导出表达式的精确性。

| Abstract: | The source and terminal a two-hop relay system are equipped with multiple antennas,while the relay only has a single antenna.OSTBC strategy is employed at the source,thus to achieve space diversity,wihle selection-and-combination is used at the terminal.To reduce the complexity of relay,the fixed-gain amplify-to-forward relaying protocol is adopted.The expression of total received SNR is derived for the case that the direct communication link exists.Also,the closed-form expression for outage probability is ... |
