A method of processing of a OFDM signal comprising a central part (10, 20b, 22b) centred on a carrier frequency, a lower sideband (12, 20a) below the lowest frequency of the central part and an upper sideband above the highest frequency of the central part (14, 22a), the method comprising: determining if the central part is analogue or digital based on the central part; initial frequency shifting of the lower sideband (12, 20a) to be immediately above the carrier frequency and of the upper sideband (14, 22a) to be immediately below the carrier frequency; filtering the initial frequency-shifted signals and performing co-channel interference compensation; filtering out the central part; further processing the initial frequency-shifted signals to derive a first reconstructed signal if the central part is analogue and a second reconstructed signal if the central part is digital; performing sample rate conversion of the first or second reconstructed signal to lower a sampling frequency to a lowered sampling frequency which depends on whether the central part is analogue or digital; FFT processing the first reconstructed signal or the second reconstructed signal; and OFDM processing the FFT processed signal, wherein if the central part is analogue, the further processing comprises: second frequency shifting of the initial frequency shifted lower sideband to be centred on the carrier frequency and of the initial frequency shifted upper sideband to be centred on the carrier frequency; filtering the second frequency-shifted signals for channel selectivity and removal of an out-of-band residual of the co-channel interference compensation; third frequency shifting of the lower sideband to be at a specific frequency above the carrier frequency and of the upper sideband to be at a specific frequency below the carrier frequency; and combining the third frequency shifted upper and lower sidebands to derive the first reconstructed signal. determining if the central part is analogue or digital based on the central part; initial frequency shifting of the lower sideband (12, 20a) to be immediately above the carrier frequency and of the upper sideband (14, 22a) to be immediately below the carrier frequency; filtering the initial frequency-shifted signals and performing co-channel interference compensation; filtering out the central part; further processing the initial frequency-shifted signals to derive a first reconstructed signal if the central part is analogue and a second reconstructed signal if the central part is digital; performing sample rate conversion of the first or second reconstructed signal to lower a sampling frequency to a lowered sampling frequency which depends on whether the central part is analogue or digital; FFT processing the first reconstructed signal or the second reconstructed signal; and OFDM processing the FFT processed signal, wherein if the central part is analogue, the further processing comprises: second frequency shifting of the initial frequency shifted lower sideband to be centred on the carrier frequency and of the initial frequency shifted upper sideband to be centred on the carrier frequency; filtering the second frequency-shifted signals for channel selectivity and removal of an out-of-band residual of the co-channel interference compensation; third frequency shifting of the lower sideband to be at a specific frequency above the carrier frequency and of the upper sideband to be at a specific frequency below the carrier frequency; and combining the third frequency shifted upper and lower sidebands to derive the first reconstructed signal. second frequency shifting of the initial frequency shifted lower sideband to be centred on the carrier frequency and of the initial frequency shifted upper sideband to be centred on the carrier frequency; filtering the second frequency-shifted signals for channel selectivity and removal of an out-of-band residual of the co-channel interference compensation; third frequency shifting of the lower sideband to be at a specific frequency above the carrier frequency and of the upper sideband to be at a specific frequency below the carrier frequency; and combining the third frequency shifted upper and lower sidebands to derive the first reconstructed signal.
