a method for controlling code power levels of individual codes of a composite quadrature phase shift keyed signal . the method may involve obtaining a sample of the composite qpsk signal ; separating the individual codes from the composite qpsk signal ; analyzing the individual codes against corresponding commanded code power settings for the individual codes ; and determining a code power correction signal needed for each of the individual codes needed to adjust a code power for each of the individual codes to match their corresponding commanded code power settings .
