Abstract

The subcarriers in an OFDM communication system or OFDM-based multicarrier communication system are multiplied with weighting factors, determined so that in accordance with an optimization criterion the side lobes are minimized in a determined frequency domain. In determining the weighting factors constraints can be taken into account to further boost system power output.
