| 摘 要： | 对于双向中继系统,在某些场景下3时隙方案的传输速率高于2时隙方案,为此提出了3时隙的多用户双向中继系统,该系统包含一个基站、若干用户和一个中继节点。基站和被选择的一个用户通过中继节点进行信息交换,用户选择的准则是使得系统的平均传输速率最大化。从理论上分析了该方案的平均传输速率,仿真得到的平均传输速率与理论值非常接近,验证了理论分析的正确性。

| Abstract: | For two-way relay system, the transmission rate over three time slot is higher than over two time slot on certain scene. Therefore, this paper proposed multiuser two-way relay system over three time slot, which consisted of a base station, several users, and a relay node. Base station and one selected user exchange information with the help of the relay node, and the user selection criterion was to maximize the system average transmission rate. It analyzed the average transmission rate theoretically. It is very closed to that by simulated, which demonstrates the validity of theoretical analysis. |
