Abstract:
1. 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.
