【摘要】：在差分调制解调的信号模型下,提出了高铁场景下2种多天线分集接收模型——线性合并分集接收和统计合并分集接收,从而得出高铁场景下车地无线宽带通信较有效的分集接收方案,提升系统性能。数学分析和仿真结果表明,所提出的线性合并分集和统计合并分集都可以通过增加分集数来降低高速移动带来的误码率平层,统计合并分集的性能要优于线性合并分集,但是其接收机复杂度也比线性合并分集要高。在实际应用中可以根据QoS的要求在性能和复杂度之间进行折衷。
[Abstract]:Under the signal model of differential modulation and demodulation, two kinds of multi-antenna diversity receiving models in high-speed railway scenario, linear merge diversity reception and statistical combination diversity reception, are proposed. As a result, a more effective diversity receiving scheme for vehicle-to-ground wireless broadband communication under high-speed rail scenario is obtained, and the performance of the system is improved. The mathematical analysis and simulation results show that the proposed linear merge diversity and statistical merge diversity can reduce the bit error rate parity layer caused by high-speed movement by increasing the number of diversity, and the performance of statistical merge diversity is better than that of linear merge diversity. However, the complexity of the receiver is also higher than that of linear merge diversity. In practical applications, the tradeoff between performance and complexity can be made according to the requirements of QoS.
