Abstract:
In one aspect, a method includes performing a mapping on bits to form a complex data symbol, applying a frequency rotation mask to the complex data symbol based on a polynomial phase, performing an inverse discrete Fourier transform (IDFT) after applying the frequency rotation mask, applying a time domain window after performing the IDFT, converting digital data to analog data after applying the time window and transmitting the analog data as an analog signal.
