A RAKE receiver for receiving a data signal transmitted from a transmitter in a spread spectrum communication system includes a symbol combiner having an adder for adding Walsh index output values, sequentially generated from a correlator using a fast Walsh transform algorithm according to N Walsh code sequences, to a value generated from a last stage of an N-stage shift register, and having the N-stage shift register for shifting an accumulated value of an output of a RAKE receiver corresponding to each index for a Walsh symbol generated from the adder each time a rake is assigned to each finger. The RAKE receiver also includes a first decision logic unit for determining a maximum value by sequentially sorting an output of the symbol combiner and generating a Walsh index corresponding to the determined maximum value as a code word; and a second decision logic unit for sorting and subtracting the output of the symbol combiner according to a state of each bit of a corresponding index and generating a probability value for the code word.

Abstract:
An image sensor is provided including a pixel array, a correlated double sampling (CDS) unit, an analog-digital converting (ADC) unit, a control unit, and an overflow power voltage control unit. The pixel array includes at least one unit pixel that generates accumulated charges corresponding to incident light in a photoelectric conversion period and outputs an analog signal based on the accumulated charges in a readout period. The CDS unit generates an image signal by performing a CDS operation on the analog signal. An ADC unit converts the image signal into a digital signal. A control unit controls the pixel array, the CDS unit, and the ADC unit. An overflow power voltage control unit controls an overflow power voltage to have a low voltage level in the photoelectric conversion period and controls the overflow power voltage to have a high voltage level in the readout period.
Abstract:
An apparatus is operable to control power of a base station in a distributed Multiple Input Multiple Output (MIMO) wireless communication system. At least one beamforming matrix is used for processing transmission signals to terminals included in a terminal set for a multiple access is determined. Minimum power values required for satisfying a minimum transmission rate of the terminals are determined. Whether optimum power values exist is determined using the minimum power values, the beamforming matrix, and a limit transmission power of the base station. When the optimum power values exist, transmission power values for respective terminals are determined in a range meeting the limit transmission power of the base station.
