Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A method of generating a waveform, the method comprising:
multiplexing, via a communication system, a first modulated signal with a second modulated signal, to generate a multiplexed signal, wherein:
a different modulation is applied in each zone of a plurality of zones,
the first modulated signal is from a first zone of the plurality of zones,
the second modulated signal is from a second zone of the plurality of zones, and
a particular zone is determined according to a proximity to the communication system;

performing a rotation operation, via the communication system, on the multiplexed signal to produce a rotated data signal;
transforming, by the communication system, the rotated data signal using a Fourier transform to produce transformed data;
mapping, by the communication system, the transformed data to a predefined number of subcarriers to produce a mapped data sequence; and
processing, by the communication system, the mapped data sequence to generate the waveform.
