Power Modification of Transmitted Symbols

An apparatus comprising:

• a wireless transmitter module configured to transmit wireless signals;
• and
• a processor configured to:
• obtain a plurality of symbols encoding data to transmit wirelessly, wherein each symbol of the plurality of symbols includes a respective magnitude;
• determine a total power to transmit the plurality of symbols;
• generate a plurality of transformed symbols by applying a transformation to the plurality of symbols, the transformation lowering a Peak to Average Power Ratio (PAPR) for the plurality of transformed symbols by adjusting the respective magnitude of at least one transformed symbol among the plurality of transformed symbols;
• generate a plurality of rescaled symbols by adjusting the respective magnitude of each transformed symbol in the plurality of transformed symbols by a scaling factor that preserves the total power to transmit the plurality of symbols;
• and
• cause the wireless transmitter module to transmit the plurality of rescaled symbols.

One or more non-transitory computer readable storage media encoded with software comprising computer executable instructions and, when the software is executed on a processor of a transmitter device, operable to cause the processor to:

• obtain a plurality of symbols encoding data to transmit wirelessly, wherein each symbol of the plurality of symbols includes a respective magnitude;
• determine a total power to transmit the plurality of symbols;
• generate a plurality of transformed symbols by applying a transformation to the plurality of symbols, the transformation lowering a Peak to Average Power Ratio (PAPR) for the plurality of transformed symbols by adjusting the respective magnitude of at least one transformed symbol among the plurality of transformed symbols;
• generate a plurality of rescaled symbols by adjusting the respective magnitude of each transformed symbol in the plurality of transformed symbols by a scaling factor that preserves the total power to transmit the plurality of symbols;
• and
• cause the transmitter device to transmit the plurality of rescaled symbols.
