System, method and apparatus to reduce error in unused tones in partial bandwidth wireless transmission system

A method comprising:

• generating selected compensation sets iteratively, for each of a plurality of resource units (RUs) of a partial bandwidth network by:
• generating, in a device under test having an integrated circuit comprising a transmitter, a test signal for one of the plurality of RUs of the partial bandwidth network;
• iteratively, for each of a plurality of candidate compensation sets:
• compensating, in the device under test, the test signal with a candidate compensation set to generate a compensated test signal;
• transmitting, from the device under test, the compensated test signal;
• measuring and logging unused tone error information associated with the compensated test signal for other RUs of the partial bandwidth network;
• selecting from one of the candidate compensation sets a selected compensation set responsive to the selected compensation set enabling a smallest unused tone error in an image frequency of the one of the plurality of RUs compared to other compensation sets of the candidate compensation sets;
• generating a reduced number of the selected compensation sets to reduce storage requirements in the integrated circuit by determining compensation sets of the selected compensation sets that can be used by multiple RUs including selecting a compensation set to be used for both a first RU and a second RU where the first RU is bigger than the second RU and the second RU is within the first RU;
• and
• storing the reduced number of the selected compensation sets into a storage in the integrated circuit.
