| 摘 要： | 协作通信可以使单天线的移动终端共享它们的天线而产生虚拟多发射天线阵列以获得发射分集.提出了一种在频率选择性衰落信道条件下的协作分集方法,信宿不仅利用转接节点转发的信号而且还利用了信源直接传来的信号来进行解码.通过计算机仿真,比较了考虑信源到信宿的直接传榆的协作方法和未考虑信源到信宿的直接传输的协作方法的误比特率性能.结果表明,考虑信源到信宿的直接传输可提高系统的协作分集增益.

| Abstract: | Cooperative communication can make single-antenna mobiles share their antennas and generate a virtual multiple-antenna array in order to achieve transmit diversity.In this paper,a cooperative diversity method in broadband wireless networks is proposed,in which the destination node utilizes the signal transmitted by the source node and relayed by relay nodes and the signal directly from the source node to decode.the performance of the error bit rate for the method proposed with direct transmit from the sourc... |
