Title: Digital optical repeater applied peak power reduction and digital pre-distortion algorithm
Inventor: CHOI GYEONG HO
IPC: H04B10/29
Filed: 2002-09-02
Abstract: PURPOSE: A digital optical repeater employing a peak power reduction and digital free distortion algorithm is provided to obtain relatively high output power compared to use of a power amplifier by reducing instantly generated peak power, increase power efficiency of the power amplifier, and considerably reduce the amount of heat releasing of a transmitter. CONSTITUTION: A doner unit(100) includes a digital signal processor(110) and an E/O(Electronic/Optical) converter(120). A remote unit(200) includes an O/E converter(210), a digital signal processor(230) and an RF unit(250). A base station transmits signals which have been modulated to QPS signals usually as an output of 20W. The digital signal processor(110) converts the signal inputted from the base station into a digital signal and reduces peak power of the digital signal. After the digital signal passes through a PPR(Peak Power Reducing) processor(111), a DPD(Digital Pre-Distortion) unit(113) applies a certain distortion signal to the digital signal. The digital signal, which has passed through the digital signal processor(110) having the PPR processor(111) and the DPD unit(113), is converted into an optical signal in the E/O converter(120) and then transmitted to the remote unit(200) connected to an optical cable.

Title: Method of auto control a volume in Mobile phone
Inventor: CHA SEONG IL
IPC: H04B1/40
Filed: 2002-09-02
Abstract: PURPOSE: A method for automatically controlling a sound volume of a mobile communication terminal is provided to automatically controlling a sound volume of a microphone according to user's controlling of speaker sound volume by making a speaker and a microphone interwork. CONSTITUTION: When a user selects a side button for controlling a sound volume(S1), a controller of a mobile phone switches a sound volume control signal transmission path to a variable amplifier of a speaker and discriminates a sound volume button selected by the user(S2). If the selected sound volume button is a sound volume up button, the controller increases a signal amplification degree of the variable amplifier to turn up the sound volume(S3). If the selected sound volume button is a sound volume down button, the controller decreases the signal amplification degree of the variable amplifier to turn down the sound volume(S4). The controller calculates a sound volume adjust value of a microphone by applying the controlled speaker sound volume value to an equation set for providing an optimum communication environment(S5). The signal amplification degree of the variable amplifier is varied to automatically perform a sound volume to turn up or turn down the sound volume of the microphone(S6).
