An apparatus and method for controlling a transmit power of a sounding signal in a wireless communication system are provided. The method includes estimating a downlink Carrier to Interference and Noise Ratio (CINR) using at least one signal received from a Base Station (BS), determining a transmit power level for a sounding signal using a target CINR for the sounding signal, wherein the target CINR is determined based on the downlink CINR and multi-target CINR information, and transmitting the sounding signal according to the transmit power level.

Provided is an apparatus and method for enhancing a demodulation performance of a receiver in a Broadband Wireless Access (BWA) system. A receiving apparatus in a broadband wireless communication system includes an estimator, a first calculator, and a second calculator. The estimator estimates a desired signal. The first calculator calculates a correlation matrix of a signal obtained by eliminating the estimated desired signal from a Received (RX) signal. The second calculator performs an interference elimination using the correlation matrix.

An apparatus and method for combining images of a mobile terminal that receives broadcast image signals. A capture module is used for capturing and storing a specific scene of a broadcast image; a first processor is used for selecting a first image of images stored in the terminal, converting the first image into a translucent image, scaling down the first image, or extracting an object image from the first image; and a second processor is used for selecting a second image of the images stored in the terminal and overlapping the scaled-down image or the object image onto the second image.

An apparatus and a method for determining an optimum integer perturbation vector of a low complexity in a multiple antenna system include a transmitter that transmits data using an optimum integer perturbation vector of a low complexity in a multiple antenna system includes a module pre-processor, a shift pre-processor, and a precoder. The modulo pre-processor adds an integer perturbation vector to a transmission signal vector. The shift pre-processor phase-shifts a pseudo inverse matrix of a channel matrix using a phase angle. The precoder precodes a transmission signal vector perturbed by the integer perturbation vector using the phase-shifted pseudo inverse matrix of the channel matrix.

A self-magnetizing motor incorporates a control circuit that starts the motor, controls a magnetizing unit, and then operates the motor. The control circuit can include relay, such as a bi-directional conductive power semiconductor device, and one or more PTC (Positive Temperature Coefficient) switches. This control circuit eliminates the need for a separate controller and the implementation costs can be reduced.
