This paper addresses multicarrier communications over the additive white Gaussian noise channel under a power spectral density (PSD) constraint. Depending on the shape of the PSD mask, straightforward power loading according to the waterfilling principle may yield poor throughput results. Several information processing techniques have been proposed to enhance the spectral properties of a multicarrier transmit signal and consequently increase the resulting throughput. Two promising spectral shaping techniques that require information processing exclusively in the transmitter are spectral compensation and intersymbol transmit windowing. This work presents prerequisites for a fair comparison and a performance assessment of these techniques
