US Patent 7792213 Minimum IQ value limiting

Embodiments of a multi-point push-out method are disclosed for a more accurate adjustment of minimum IQ values in order to maintain better continuity in the IQ trajectory for sampled IQ values near the origin. IQ trajectories near the origin are limited to a minimum IQ value by determining a specific scaling factor according to a position of the sampled IQ value relative to the origin and/or to the minimum IQ value. The minimum IQ value is also referred to as a threshold boundary value.
