Title: Innovations of Suchang Chae in MIMO Systems
Introduction
Suchang Chae is a notable inventor based in Daejeon, South Korea. He has made significant contributions to the field of telecommunications, particularly in the area of multiple input multiple output (MIMO) systems. With a total of 2 patents, his work focuses on enhancing communication technologies.
Latest Patents
One of his latest patents is titled "Method and apparatus for generating common signal in multiple input multiple output system." This invention provides a method for a base station to generate a common signal required for surrounding terminals in a massive MIMO system. The base station creates data that is essential for the surrounding terminals and generates multiple beamforming vectors using a time-domain constant amplitude and frequency-domain constant amplitude sequence. Additionally, the base station produces several antenna streams corresponding to the common signal by multiplying the beamforming vectors with the data.
Another significant patent by Suchang Chae is "Method and apparatus for mapping virtual antenna to physical antenna." In this invention, a transmitter generates a first precoding vector for a virtual antenna port using a sequence with constant magnitude and a discrete Fourier transform vector sequence. The transmitter also creates multiple second precoding vectors for the remaining virtual antenna ports by circular shifting the first precoding vector. This process allows for the mapping of data streams from virtual antenna ports to physical antenna ports effectively.
