1. A receiver, comprising:

  • an Orthogonal Frequency Division Multiplexing (OFDM) demodulator configured to perform a first discrete Fourier transform (DFT) to demodulate a spread-OFDM signal transmitted from a user equipment (UE), to produce a plurality of demodulated data symbols corresponding to a plurality of OFDM subcarriers assigned to the UE; and

    a DFT-based despreader configured to perform a second DFT to despread the demodulated data symbols to produce estimates of original data symbols, wherein the despreader employs a DFT despreading code corresponding to a DFT spreading code employed by the UE.
