Latest Patents

Kai Xie's latest patents focus on stable modulation index calibration and dynamic control. The process involves generating a training sequence of bits, shaping a pulse from this sequence according to an initial modulation index, and converting the shaped signal into a transmission signal. This transmission signal can either be looped through a radio frequency core or processed by frequency deviation estimation hardware to determine a frequency deviation. The frequency deviation is then converted to a new modulation index, and potentially a ratio between a target modulation index and a measured modulation index is used as a scaling factor. This iterative process continues until a threshold frequency deviation is achieved.
