The coarse layer contains an alkaline-resistant cellulose fiber having a freeness value of 350 to 650 ml as a whole in the proportion of 25 to 65% by weight. The alkaline-resistant cellulose fiber includes at least two kinds of alkaline-resistant cellulose fibers having different freeness with each other. The difference in freeness value between the alkaline-resistant cellulose fibers having the highest and lowest freeness values is 300 to 700 ml.

    摘要: A disclosed receiver in a MIMO multiplexing communication system, in which plural signals are simultaneously transmitted from plural transmitting antenna branches using the same frequency, and the transmitted signals are retrieved by receiving signals at plural receiving antennas, separating the received signals and searching for proper symbol metrics for each branch, comprises a QR decomposer for QR decomposing the received signals to orthogonalize the transmitted signals; a symbol replica candidate ranking unit for subtracting surviving symbol replica candidates from the QR decomposed received signals to get remaining received signals and rank the remaining signals in the increasing order of expected branch metrics of the remaining received signals; a symbol replica candidate selector for selecting symbol replica candidates in the ranked order; a branch metric calculator for calculating the branch metrics of the selected symbol replica candidates; and a threshold comparator for comparing the calculated branch metrics with a predetermined threshold; wherein if a calculated branch metric is larger than the predetermined threshold, the branch metric and successive branch metrics are deleted without further searching.
