Introduction

Ji-Won Kang is a prominent inventor based in Incheon, South Korea. He has made significant contributions to the field of wireless communication, holding three patents that showcase his innovative approach to technology.

Latest Patents

One of his latest patents is a "Beam forming method and apparatus." This invention relates to a method of forming a random beam and a beam forming apparatus. It utilizes a quantization preprocessor and a random unitary matrix with a predetermined pattern to form a beam on a mobile terminal. A base station forms a beam using a codeword index from a quantization codebook received from the mobile terminal, along with channel quality information. The mobile terminal generates this information using pilot signals from the base station, which are equal to the number of transmitting antennas. This method allows for the selective giving of diversity, thereby improving system efficiency.

Another notable patent is the "Precoding device and method in a wireless communication system." This invention addresses the challenges of multi-user multi-antenna communication systems. It involves a precoder and a precoding method that prevent system performance degradation caused by interference signals. The method efficiently reduces transmission power while changing the constellation rotary angle, enhancing system performance without compromising the structural gain of existing multi-user multi-antenna precoders.
