| 摘 要： | 空间调制是未来5G蜂窝通信系统的物理层备选技术之一,为研究LLL、嵌入式两种格基规约算法对空间调制技术的影响,设计了两种检测方案,分别为LLL辅助MMSE检测方案和嵌入式检测方案.在不同的调制符号、不同的天线数目下,通过仿真比较两种检测方案的误比特率性能.然后通过矩阵运算理论对两种检测方案的运算复杂度进行分析,为使分析结果更直观,在不同天线数目下,对两种方案的运算复杂度进行了仿真.理论分析和仿真结果表明,嵌入式检测方案在误比特率和运算复杂度两方面均优于LLL辅助MMSE检测方案,它更适用于空间调制技术.

| Abstract: | Spatial modulation is one of the alternative physical layer technologies in 5G cellular communication system. To study the influence of LLL algorithm and augmented lattice reduction on the bit error rate and computational complexity of spatial modulation, two schemes are proposed, which are called LLL aided MMSE detection scheme and augment detection scheme. With different modulation symbols and different antenna numbers, the error rate of the two detection schemes is compared by simulation. Then, the computational complexity of the two detection schemes is compared by the matrix operation analysis. To make the analysis result more intuitive, the simulation with different antenna numbers is executed. Theoretical analysis and simulation results show that in the aspect of bit error rate and computational complexity, the augment detection scheme excels the LLL aided MMSE detection scheme. Therefore, the augment detection scheme is more suitable for spatial modulation technology. |
