Title: Gi-Hong Im: Innovator in Wireless Communication Technology

Introduction

Gi-Hong Im is a prominent inventor based in Pohang-si, South Korea, known for his significant contributions to wireless communication technology. With a total of eight patents to his name, he has made remarkable advancements in the field, particularly in signal transmission and reception.

Latest Patents

Among his latest patents is an "Apparatus and method for transmitting and receiving a signal in a wireless communication system." This invention involves a wireless communication system that includes a transmitter with at least four transmit antennas and a receiver with at least one receive antenna. The system utilizes Space Frequency Block Coding (SFBC) processes for input signals based on two antenna pairs, outputting signal blocks corresponding to the number of transmit antennas. Additionally, a Space Time Block Coding (STBC) process is performed for the generated signal blocks, allowing for efficient signal transmission through the multiple antennas.

Another notable patent is the "Inter-carrier interference cancellation method and receiver using the same in a MIMO-OFDM system." This invention provides a receiver for ICI cancellation in a MIMO system, where a detection orderer determines a subcarrier detection order based on the Signal-to-Interference-plus-Noise Ratios (SINRs) of subcarriers. The detector iteratively estimates the received vector using a priori information, leading to the decoding of an ICI-cancelled signal.
