Abstract
A poly-phase frame modulation system includes a phase matrix look-up table being configured for generating a reference phase matrix; a first phase modulator being configured for generating a first modulated output by taking in the data from a red channel and the sum of the reference phase matrix and a frame offset; a second phase modulator being configured for generating a second modulated output by taking in the data from a green channel and the sum of the reference phase matrix, the frame offset and a first channel offset; and a third phase modulator being configured for generating a third modulated output by taking in the data from a blue channel and the sum of the reference phase matrix, the frame offset and a second channel offset.
