ABSTRACT:
An OFDM transmitter generates FSK symbols in a communications network. Complex values representing OFDM tones are partitioned in groups. A distinct energy is assigned to each group of complex values. An OFDM modulator is applied to the complex values having the assigned distinct energies to generate FSK symbols corresponding to the groups, and the FSK symbols are transmitted serially.
