Title: Ju Bum Kim: Innovator in Data Transformation and Interference Alignment
Introduction
Ju Bum Kim is a notable inventor based in Gyeongsangbuk-do, South Korea. He has made significant contributions to the fields of data transformation and interference alignment, holding a total of three patents. His work focuses on enhancing communication systems by addressing issues related to data interference.
Latest Patents
One of Ju Bum Kim's latest patents is a "Method and apparatus for transforming data symbol for interference avoidance." This invention discloses a method that involves dividing a plurality of proper data symbols into multiple data streams. It grants individual spectral weightings to these data streams and combines them into a final data stream. The process includes performing an inverse discrete Fourier transform (IDFT) and adding a cyclic prefix to the data streams subjected to the IDFT. Each data stream incorporates an improper data symbol, which is crucial for minimizing interference.
Another significant patent is the "Method and apparatus of interference alignment in cellular network." This invention outlines a method where a base station receives an improper signal from a terminal and decodes it using an improper decoding vector. The improper signal is generated by a modulation symbol corresponding to a real number value. The decoding vector is determined based on an improper precoding vector, which separates the real number space from the imaginary number space of the received signal.
