Introduction

Jin-Bong Chang is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the field of data transmission and communication technologies. With a total of 8 patents to his name, Chang's work has had a considerable impact on the efficiency of data communication systems.

Latest Patents

One of his latest patents is a data transmission method using packet aggregation. In this method, a MAC layer receives data from an upper layer, classifies the data according to destination addresses and traffic identifiers, aggregates the data by destination address and traffic identifier as a first transmission unit, aggregates the first transmission units having the identical destination address as a second transmission unit, and transmits the second transmission units having different destination addresses in a single frame. This innovative approach allows packets transferred from the upper layer to be hierarchically aggregated by destination addresses and traffic identifiers, enabling optimal data transmission rates for each destination terminal.

Another notable patent is a data communication method based on multi-receiver aggregation. This wireless communication system includes transmitters that determine a transmission rate for an associated receiver according to channel state information fed back from the receivers. The transmitter groups packets to be transmitted according to these transmission rates and generates frames configured by packets with identical transmission rates. By aggregating frames with different transmission rates into one transmission burst, this method efficiently manages resources and enhances communication efficiency.
