Latest Patents

One of his latest patents is titled "Apparatus and method for transmitting signal in wireless communication system." This invention relates to an apparatus and method for transmitting a signal using a power amplifier in a wireless communication system. The transceiver in this system includes a digital pre-distorter that distorts an input signal based on a distortion control value. It also features a power amplifier that amplifies the output signal from the digital pre-distorter, an antenna for transmitting the output signal, and an echo signal canceller that removes echo signals returning to the power amplifier. Additionally, a digital pre-distortion adaptation unit determines the distortion control value based on the output signal from the echo signal canceller.

Another significant patent by Hong is "Apparatus and method for controlling output of base station in mobile communication system." This method involves measuring the Received Signal Strength Indication (RSSI) and receive sensitivity of at least one macro base station and a neighboring small base station. It determines the service margin of the small base station and adjusts the transmission power based on the RSSI, receive sensitivity, and service margin. The method may also include extracting the receive sensitivity of the neighboring small base station and calculating the RSSI of the macro base station from total RSSIs based on a receive sensitivity ratio.
