Spectral precoding is effective in reducing out-of-band radiation
(OBR) in multicarrier systems, but it introduces distortion
in the data, requiring a suitable decoder at the receiver.
Thus, trading off OBR reduction, implementation complexity,
and error rate is of paramount importance. We present a precoder
design which minimizes OBR under constraints on the
distortion at each individual data subcarrier. By judiciously
choosing the distortion profile, the decoding task can be significantly
alleviated, with a sizable improvement in terms of
implementation complexity with respect to previous designs.
