摘要

滤波器组多载波(FBMC)调制在第五代(5G)无线通信系统中被认为是重要的，因为它比传统的正交频分复用(OFDM)具有更高的频谱效率。本文将一种基于SISO因子图的最大后验(MAP)检测器应用于FBMC系统。该检测器在编码系统中具有比简单的最小均方误差(MMSE)和零强迫(ZF)均衡器更好的性能。它的计算复杂度随着干扰的数量线性增长，这意味着在性能和复杂度之间取得了很好的平衡。仿真结果表明，该检测器具有良好的性能。并对其复杂性进行了分析

Graph-based detectors for filter bank multicarrier systems

Filter Bank Multicarrier (FBMC) modulation is thought to be important in 5th generation (5G) wireless communication systems for its higher spectral efficiency than conventional orthogonal frequency division multiplexing (OFDM). In this paper, we apply a kind of soft-input-soft-output (SISO) factor-graph-based maximum-a-posterior (MAP) detector in FBMC systems. The detector has better performance than simple minimum mean square error (MMSE) and zero forcing (ZF) equalizers in coded systems. Its computational complexity grows linearly with the number of interferences which means a good tradeoff between performance and complexity. The simulation results show the good performance of the detector. And the complexity is also analyzed in this paper.1
