Abstract

We consider a mobile-to-mobile (M2M) communication scenario in a crowded city or suburban area, where each mobile terminal is surrounded by a group of scatterers. The non-line of sight (NLOS) communication channel is modelled as non-frequency selective double or cascaded Rayleigh distributed. Cooperative relaying with amplify and forward (AF) protocol is used to improve the overall system performance. System performance is investigated in two sets. In the first case, the source (S) to destination (D) direct link is double Rayleigh distributed. The relay (R) or access point is assumed to be located above rooftop level and the cooperative links are flat Rayleigh faded. In the second case, both the direct and cooperative links are considered double Rayleigh faded. Modelling and simulations are used to evaluate overall performance in conditions, when the cooperative link is uncorrelated, partially correlated and completely correlated with the direct link.

双瑞利衰落或级联瑞利衰落下中继辅助移动对移动通信的性能分析

我们考虑在拥挤的城市或郊区的移动到移动(M2M)通信场景，其中每个移动终端都被一组分散器包围。将非瞄准线通信信道建模为非频率选择性双瑞利分布或级联瑞利分布。采用放大转发(AF)协议的协同中继，提高了系统的整体性能。系统性能分为两组进行研究。在第一种情况下，源(S)到目的(D)的直连链路为双瑞利分布。假设中继(R)或接入点位于屋顶以上，合作链路是平坦的瑞利衰落。在第二种情况下，直接联系和合作联系都被认为是双重瑞利褪色。通过建模和仿真来评估合作链路与直接链路不相关、部分相关和完全相关三种情况下的整体性能。
