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

Claim 10:
11. A communication system to generate a waveform in a communication network, the system comprising:
a multiplexer configured to multiplex a first modulated signal with a second modulated signal to generate multiplexed data, 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;

a memory; and
a processor, communicatively coupled to the memory, configured to:
perform a rotation operation on the multiplexed data to produce a rotated data;
transform the rotated data using a Fourier transform to produce transformed data;
map the transformed data using a predefined number of subcarriers to produce a mapped data sequence; and
process the mapped data sequence to generate a waveform.
