| 摘 要： | 针对散射传输系统在传播过程中存在传输损耗较大、多径衰落严重、信道特性多变的问题,着重对混合式分集合并及其性能进行了分析.首先对分集合并技术进行了简要介绍,然后分析了混合式合并的信噪比和误码率性能,并与选择性合并、等增益合并和最大比合并进行了比较.理论与仿真结果表明,在分集重数较多的情况下,混合式合并能简化散射通信系统的设备复杂度,同时又能够得到较好的合并效果.

| Abstract: | Aimed at the actual problems of scatter transmission system that are of more transmission loss,bad multi-path fading and variable characteristics of channel,this paper analyzes emphatically the hybrid diversity combination technique and its performances.Firstly,the diversity combination is briefly introduced,then,the performance of SNR and BER for hybrid combination analyzed,and finally the selective incorporation,equal gain combination and maximum ratio combination are compared in this paper.Both theory and simulation results show that the hybrid combination can not only simplify the scatter transmission system,but also gain better combining effect in the condition of more diversity tuples. |
