为了克服现有信道模型的局限性,更灵活地描述城市密集弯道车对车(CarGtoGCar,C2C)传播环境下通信系统的传输特性,构建了一种新型宽带多入多出系统(multipleGinputmultipleGoutput,MIMO)衰落信道模型.模型中散射体分布于弯曲道路外侧的固定弧形区域内,考虑了到达角(angleofarrival,AOA)和发射角(angleofdepartare,AOD)之间的准确关系,推导了散射信道的空间、时间频率互相关函数(spaceGtimeGfrequencycrossGcorrelationfunction,STFGCCF)的解析表达式;分析了模型参数及散射体分布等因素对C2C通信系统性能的影响.仿真结果与一些经典模型数据及测量信道对比,表明了该模型的合理性与可行性.
In order to overcome the limitation of the existing channel model and describe the transmission characteristics of the communication system under the environment of CarGtoGCar (C2C) communication more flexibly, a new multiple input multiple output MIMO system ) Fading channel model, the scatterers are distributed in the fixed arc outside the curved road, and the accurate relationship between the angle of arrival (AOA) and the angle of emission (AOD) is deduced, and the space of the scattering channel is derived , And the time-frequency cross-correlation function (STFGCCF). The influence of model parameters and scatterer distribution on the performance of C2C communication system is analyzed. The simulation results are compared with some classical model data and measurement channel, which shows that the model The rationality and feasibility of
