1. An OFDM system comprising:

  • a transmitter configured to transmit an orthogonal frequency division multiplexing (OFDM) signal in which side lobes of said signal are suppressed by a pulse shaping operation performed by a pulse shaping mechanism on said signal, said pulse shaping operation causing a loss of carrier orthogonality; and

    a receiver configured to receive said signal, said receiver comprising an equalizer configured to compensate for said loss of orthogonality.
