| Abstract | Spectral precoding is effective in reducing out-of-band radiation(OBR) in multicarrier systems, but it introduces distortionin 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 precoderdesign which minimizes OBR under constraints on thedistortion at each individual data subcarrier. By judiciouslychoosing the distortion profile, the decoding task can be significantlyalleviated, with a sizable improvement in terms ofimplementation complexity with respect to previous designs. |
