Method, device and system of reduced peak-to-average-ratio communication

A system comprising:

• a wireless transmitter to transmit a wireless transmission corresponding to an input video signal, said transmitter comprising:
• a data-component mapper to map a plurality of data components representing said video signal into a plurality of fine-constellation data components and a plurality of coarse-constellation data components;
• a peak-to-average-ratio-reduction transformer to generate a plurality of transformed data components by applying to said plurality of fine constellation data components a predefined peak-to-average-ratio-reduction transform scheme, wherein a peak-to-average-ratio corresponding to said plurality of transformed data components is lower than a peak-to-average-ratio corresponding to said plurality of fine-constellation data components;
• and
• a radio-frequency module to generate said wireless transmission based on said plurality of transformed data components and said plurality of coarse-constellation data components;
• and
• a wireless receiver to receive said wireless transmission and to generate an output video signal corresponding to said wireless transmission.
