US Patent 7724190 Signaling method and apparatus using radial interplex

Embodiments of the disclosure provide methods, apparatus, and articles related to code combination for GPS III, and more particularly, to methods and apparatuses for enabling signal modulation that potentially may minimize power throw away for target code power ratios by shifting linear signal constellation points radially to a circle of equal amplitude, e.g., where the circumference represents e.g. the average RMS power of the original linear signals.
