Patent ID: 7620129

Claim:
A method for generating control signals, comprising: a) receiving an in-phase data component and a quadrature phase data component of a time-varying complex envelope signal; b) calculating a first phase shift angle between first and second substantially constant envelope constituents of said in-phase data component; c) calculating a second phase shift angle between first and second substantially constant envelope constituents of said quadrature phase data component; d) calculating in-phase and quadrature amplitude control signals associated with said first and second constant envelope constituents of said in-phase data component; e) calculating in-phase and quadrature amplitude control signals associated with said first and second constant envelope constituents of said quadrature phase data component; and f) outputting said in-phase and quadrature amplitude control signals for said in-phase and quadraturephase data components to a vector modulation stage, wherein said vector modulation stage uses said in-phase and quadrature amplitude control signals for said in-phase and quadrature phase data components to generate substantially constant envelope constituents of said time-varying complex envelope signal.
