In this letter, a low complexity least squares-based receiver is proposed for universal filtered multicarrier systems. Specifically, the coarse estimate of the transmitted symbol is first obtained by one-tap equalization using the even components of the frequency-domain received signal. The inter-block interference is then removed from the received signal, and the out-of-subband data are punctured. Finally, a complexity-reduced approach is designed to obtain performance improvement based on the overall pre-processed data. A closed-form mean-square error expression and computational complexity analysis are derived to quantify the achievable advantages. Simulation study confirms the effectiveness of the proposed receiver.
