Title: Innovations of Hangkan Bengt Eriksson
Introduction
Hangkan Bengt Eriksson is a notable inventor based in Lund, Sweden. He has made significant contributions to the field of signal processing and modulation. With a total of four patents to his name, Eriksson's work has advanced the technology used in communication systems.
Latest Patents
One of Eriksson's latest patents is a method and apparatus for generating a linearly modulated signal using a polar modulation system. This invention separates a signal for transmission into a phase component and an amplitude component. A carrier signal is modulated with the phase component in a phase modulator, which creates a phase distortion. A compensator then compensates for this distortion by modifying the amplitude component. The phase modulated carrier signal is subsequently amplitude modulated by the compensated amplitude component to produce a linearly modulated signal.
Another significant patent is related to a post-filtered delta sigma for controlling a phase locked loop modulator. This invention includes a frequency synthesizer with a phase locked loop, a delta sigma modulator, and a filter. The phase locked loop features a frequency divider that controls the frequency of the output signal. The output of the delta sigma modulator is filtered, and this output is used to control a division factor in the frequency divider. Compensation may be performed at the input to the delta sigma modulator to address filtering issues, thereby reducing quantization noise and phase noise in the output of the phase locked loop.
