For single-carrier systems with frequency domain equalization, decision feedback equalization (DFE) performs better than linear equalization and has much lower computational complexity than sequence maximum likelihood detection. The main challenge in DFE is the feedback symbol selection rule. In this paper, we give a theoretical insight on multiple symbol selection, based on sparsity and we present a simple algorithm for DFE. The algorithm converges fast and has a low computational cost.
