Abstract
A plurality of information bits are mapped to: (i) a first plurality of constellation symbols corresponding to a first plurality of OFDM subcarriers in an OFDM symbol, and (ii) a second plurality of constellation symbols corresponding to a second plurality of OFDM subcarriers in the OFDM symbol. A first time-domain signal is generated by performing an IDFT based on the first plurality of constellation symbols. A second time-domain signal is generated by performing an IDFT based on the second plurality of constellation symbols. The first time-domain signal is modified by applying a first windowing function corresponding to a first transition width β1. The second time-domain signal by applying a second windowing function having a second transition width β2. An output signal is generated to include a sum of the first time-domain signal and the second time-domain signal, the output signal corresponding to the OFDM symbol.
