Abstract:
PURPOSE: A method for installing a home wireless communication antenna is provided to quickly and accurately determine a position for installing an antenna and perform smooth communication without causing an interference with the outside. CONSTITUTION: Two horizontal lines are drawn on a drawing(100). Central points with respect to cross points of the horizontal lines and a wall are searched and vertical lines are drawn(102). Two lines, located at the center, from vertical lines that can be transmitted in the wall are selected from vertical lines that can be transmitted in the wall (104). Vertical lines are drawn on the drawing(106). Central points with respect to cross points of the vertical lines and a wall are searched and horizontal lines are drawn(108). A center of a square formed by the two horizontal and vertical lines is searched for installation of an antenna(110). A tilting angle of the antenna and a height of the antenna from the bottom are determined(112). The antenna is installed at the corresponding position(114).
Abstract:
A decision feedback equalizer and a method for updating tap coefficients of the decision feedback equalizer are provided. The decision feedback equalizer (DFE) includes a first equalizer for reducing channel interference noise in an input signal, a second equalizer for generating a feedback signal for reducing remaining interference noise, and an update controller for controlling the first and the second equalizers so as to freeze the second equalizer when the first equalizer is updated and to freeze the first equalizer when the second equalizer is updated. The tap coefficients of the feedforward equalizer and the feedback equalizer are alternately initialized. It then becomes possible to stably converge the levels of respective tap coefficients without diverging them and to reduce the power used for updating the tap coefficients in a steady state.

Abstract:
PURPOSE: A method for encrypting/decrypting data from the terminal of a CDMA(code division multiple access) wireless communication system having data protection function is provided to keep data secret at the other places except both transmitting and receiving terminals by protecting the data with a block cipher or a cipher key. CONSTITUTION: A vocoder packet information bit is generated by coding of an input signal into a specific size of information bit. The coded vocoder packet information bit is block-encrypted. The encrypted vocoder packet information bit is formed as a CDMA frame by combination with a frame quality indicator and encoder tail bits. Finally, the CDMA frame is transmitted to a base station through a frequency band allocated in a process of convolutional encoding, interleaving and band expanding. Therefore, the CDMA frame is kept secret safely during transmitting.
