Patent ID: 7085327

Claim:
A phasor flipping component for use in a phasor fragmentation component of transmitter circuitry configured for digitally determining a plurality of equal amplitude fragment phasors representative of a non-constant envelope modulation signal, wherein said amplitude of said fragment phasors is a predetermined proportion of the variation of the amplitude of said modulation signal about the mean amplitude thereof, said phasor flipping component configured to perform a comparison of angle separations between preselected fragment phasors, as determined for each of prior and current time samples, and to swap the phases determined for said fragment phasors for a current time sample when said comparison identifies that said angle separation for a first said fragment phasor between said prior and current time samples changes from being less than to greater than the angle separation between a second said fragment-phasor for said current time sample and said first fragment phasor for said prior time sample.
