Abstract
The invention relates to an OFDM-transmitter, comprising means for transforming () data to be transmitted in frequency-to-time transformation to a basic waveform containing waveform components representing subbands of the spectrum of the signal. The transmitter comprises means for forming () at least one alternative waveform from components of the basic waveform, where at least one component in the alternative waveform is delayed in time, and means for selecting () a waveform for transmission from the group of waveforms, containing the basic waveform and the at least one alternative waveform. The invention also relates to a method for transmitting an OFDM signal, a method for processing an OFDM signal and an OFDM signal processing arrangement.
