| Title of Invention | A METHOD FOR REDUCING PEAK TO AVERAGE POWER RATIO IN A RADIO FREQUENCY SIGNAL |
|---|---|
| Abstract | A method for reducing peak to average power ration in a radio frequency signal, the method comprising the steps of modulating a plurality of subcarriers with a plurality of data symbot vectors to produce a first modulated signal; limiting the magnitude of the first modulated signal to prodcue a first limited modulated signal; and demodulating the first limited modulated signal to recover the data symbol vectors by the steps of predistorting the data symbol vectors to provide a minimum magnitude for in=phase and quadrature components thereof to produce predistorted data symbol vectors. modulating the plurality of carriers with the predistorted data symbol vectors to produce a second modulated signal; limiting the magnitude said second modulated signal to produce a second limited modulated signal; and reducing intermodulation products in said s e cond limited modulated signal. |
