    摘要： A channel quality measurement method that accomplishes efficient channel quality measurement for each mobile station is presented. In a frequency band including a plurality of frequency blocks, a base station measures the channel quality of each of a plurality of mobile stations. With respect to each mobile station, when a pilot resource for demodulation is not allocated in at least one of the frequency blocks, the base station allocates a specific pilot resource for channel quality measurement in that frequency block. The channel quality of each mobile station in the plurality of frequency blocks is measured by using one or both of the pilot resource for demodulation and the dedicated pilot resource for channel quality measurement.

    摘要： By using the maximum one of the obtained signals as maximum absolute response value signal and m sequential absolute response value signals, in which the maximum absolute response value signal is highest in response speed, as precursor candidate signal set, an absolute value signal sum as the total sum of the precursor candidate signal set is obtained. When a weighted absolute value signal sum obtained by multiplying the absolute weighted value signal sum by a shift factor determined on the basis of the received signal intensity is greater than all of preceding absolute response value signals as absolute response value signals higher in response speed than the precursor candidate signal set, n impulse response signals next in response speed to, the precursor response signal set are made to be a postcursor response signal set.

    摘要： A sign determination circuit is input with in-phase signal I, and outputs in-phase sign determination signal SPI to indicate the sign, positive or negative, of in-phase signal I. Another sign determination circuit is input with orthogonal signal Q, and outputs orthogonal sign determination signal SPQ to indicate the sign, positive or negative, of orthogonal signal Q. A decoder is input with in-phase sign determination signal SPI and orthogonal sign determination signal SPQ, judging which quadrant the vector represented by in-phase signal I and orthogonal signal Q belongs to, thereby determining I&thgr;4, I&thgr;3 to indicate the 180° bit and 90°-bit, respectively, of angle information I&thgr;. Also, I&thgr;2, I&thgr;1 to indicate the 45°-bit and 22.5°-bit, respectively, of angle information I&thgr; is given by the other decoders.
