Abstract:
An OFDM modulation process and means for transmitting multiple carriers through a communication channel having a bandwidth arranged ion chunks with further subcarriers being allocated to form at least one guard band, comprising automatically and periodically shifting said chunks to the left or to the side in order to overlap said guard band and increase spectral diversity.
