9. A detector for an SM-FBMC/OQAM system, comprising:
a decision unit configured to receive a plurality of reception signals corresponding to a subchannel from a plurality of reception antennas to output a decision signal corresponding to the subchannel and a transmission antenna;
an inter-symbol feedback filtering unit configured to feed back the decision signal corresponding to the subchannel and the transmission antenna to the decision unit for eliminating an inter-symbol interference (ISI); and
at least one inter-subchannel feedback filtering unit configured to feed back at least one decision signal corresponding to another subchannel to the decision unit for eliminating an inter-subchannel interference (ICI).
