Abstract
An OFDM signal generator includes a time domain data signal generator configured to generate a time domain data signal, a partial signal generator configured to generate a plurality of partial signals based on a tail section of the time domain data signal, and a circuit element configured to form a difference between or a sum of the time domain data signal and the plurality of partial signals.

A method for generating an OFDM data signal in an OFDM signal generator, comprising:
- forming a frequency domain data signal including determining a plurality of non-data carriers and setting the non-data carriers to zero in a frequency domain data signal generator;
- forming a time domain data signal by performing an inverse Fourier transformation of the frequency domain data signal in a time domain data signal generator;
- forming a tail section signal comprising a tail section of the time domain data signal in a tail section signal generator;
- forming a multiplied tail section signal in a multiplied tail section signal generator, by forming a plurality of partial signals, each one of the partial signals being derived from the tail section signal;
- forming a difference between or a sum of the multiplied tail section signal and the time domain data signal in a difference forming circuit, thereby generating the OFDM data signal with a guard interval associated therewith;
- and
- transmitting the OFDM data signal using a transmitter circuit.
