Title: In-Bae Kim: Innovator in OFDM Mobile Communication Systems
Introduction
In-Bae Kim is a notable inventor based in Chonen-shi, South Korea. He has made significant contributions to the field of mobile communication systems, particularly in the area of Orthogonal Frequency Division Multiplexing (OFDM). With a total of 2 patents, his work focuses on improving the efficiency and performance of communication technologies.
Latest Patents
In-Bae Kim's latest patents include innovative methods and apparatuses aimed at reducing the peak-to-average power ratio (PAPR) in OFDM mobile communication systems. One of his patents describes a block coding apparatus and method that effectively reduces PAPR to 3 dB or less. This is achieved while doubling the traditional block coding rate through the use of complementary sequences. As a result, the spectral efficiency is improved while maintaining the traditional error correction capability, facilitating easier decoding. Another patent discloses an apparatus and method for reducing PAPR caused by multiple subcarriers in an OFDM system. This involves pre-emphasizing the output signal of an Inverse Fast Fourier Transform (IFFT) block at the transmitter and de-emphasizing the received signal before Fast Fourier Transform (FFT) at the receiver, thereby efficiently addressing PAPR issues.
