摘　　要：FBMC(Filter Bank Multicarrier)modulation is considered one of the waveform candidates in fifth generation wireless communication technology because of its several improved features compared to conventional orthogonal frequency division multiplexing schemes.A soft-input-soft-output factor-graph-based maximum-a-posterior detector is applied to FBMC systems.The detector achieves better performance than simple linear equalizers such as minimum mean square error and zero forcing in coded systems while exhibiting only a linear growth in complexity with the number of simultaneous interfering symbols.Furthermore,the proposed detector can be easily extended to cases where FBMC modulation is combined with multiple-input-multiple-output processing.The complexity of the detector is analyzed and the simulation results demonstrated its superior performance.
