4×4天线分组排序K-Best MIMO检测器设计

摘要

目前K-Best MIMO检测器采用的排序选择运算占用了大量硬件资源，使得硬件设计复杂度极高。为了在保证良好的算法性能的同时还能够降低硬件设计复杂度，采用分组排序方式对排序选择运算进行了优化，并在现场可编程门阵列平台上对4×4天线、16QAM调制方式的分组排序K-Best MIMO检测器进行了仿真分析。%Traditional K-Best MIMO detector using the sort-selection computation takes up a large amount of hardware resources and makes hardware design more complex. In order to ensure good algorithm performance and reduce the hardware design complexity, the group-sort method is adopted to optimize the sort-selection computation. And then the group-sort K-Best MIMO detector with 4×4 antenna and 16QAM modulation method is simulated on FPGA platform.
