摘要 提出了一种利用改进球译码算法实现滤波器组多载波系统(FBMC)的均衡算法。对基于球译码算法的FBMC均衡算法性能进行了分析,说明了算法的最优性。并进一步推导了改进球译码算法降低经典球译码算法复杂度的基本原理。计算机仿真结果表明:改进球译码均衡算法明显优于迫零算法,在显著降低算法复杂度的同时,性能损失较小。 An equalization algorithm based on modified Sphere-decoder for FBMC is proposed in this paper. The excellence of the algorithm is analyzed. The principle of the reduction of the modified algorithm is further deduced. Computer simulations verify that the algorithm outperforms the zero-forcing algorithm, and the performance loss of the modified algorithm is comparatively small.
