    摘要: The present invention provides a precoding method for use in a wireless communications system. According to the precoding method of the present invention, a serving base station and cooperative communication base stations employ an identical precoding matrix so as to weight transmission signals and then transmit them. The weighting stands for multiplication of results of overall precoding or each layer precoding process by weight values at the serving base station and the cooperative communication base stations. A user device corresponding to the serving base station and the cooperative communication base stations receives a signal which is obtained by an operation in which the serving base station and the cooperative communication base stations perform an identical precoding process and additively combine results of overall precoding or each layer precoding process with one another. The user device feeds back information which includes (i) precoding matrix information for the serving base station and the cooperative communication base stations, (ii) weight vector information for either overall precoding or layer precoding, and (iii) a quantized value of channel quality. This feedback information is thus advantageous in that its signaling information amount is small.

    摘要: A maximum voltage selection circuit and method and a sub-selection circuit are provided. The maximum voltage selection circuit includes a peripheral signal circuit and a selection circuit with N channels of input voltages. The peripheral signal circuit provides an operating mode signal and a reference voltage to the selection circuit including N sub-selection circuits coupled to the N channels of input voltages respectively. A sub-selection circuit determines its operating mode according to the operating mode signal. In the operating mode, when an input voltage of a sub-selection circuit is larger than the reference voltage, the sub-selection circuit sets itself to the output enable state and sets other sub-selection circuits to the output disable state, and outputs its input voltage as a maximum voltage through a PMOS.
