We consider the residual interference problem for a filter bank-based multicarrier with quadrature amplitude modulation under multipath fading channels. In order to handle this problem, we propose a layered detection algorithm based on interference cancellation (IC). In proposed algorithm, we define two thresholds, a selection threshold and a region threshold for efficient IC. According to the selection threshold, we decide whether to apply IC or not, and configure a successive detection region based on the region threshold. Simulation results show that the proposed algorithm provides almost the same bit error rate performance as the orthogonal frequency division multiplexing and the criteria for the proposed thresholds are reasonable.
