| 摘 要： | 考虑蜂窝移动通信系统中大尺度衰落对协作分集技术的影响,提出根据大尺度衰落相关性来选择协作伙伴。以距离和终端所处的地理环境为依据,建立了蜂窝移动通信系统中阴影衰落的相关模型,求出各终端间的相关系数,选择相关系数最小的作为协作伙伴。从理论上对由此形成的协作通信系统进行了分析,可以提高信道容量,降低误码率。仿真结果进一步验证了该方法的可行性。

| Abstract: | Considering the effect that large-scale fading in cellular mobile communication system has on the cooperative diversity, the selection of partner based on the correlation of the large-scale fading is proposed. A correlated model of shadow-fading is established based on the distance and the geographical surroundings, and the correlative coefficients are given and the End-User with smallest correlative coefficient is selected as cooperative partner. The formed cooperative communication system is analyzed theoretically and it can improve the channel capacity and reduce the BER. The simulation results further show that the proposed method is feasible. |
