    摘要： In a multi user communication system, subcarriers are allocated to subchannels using a quality measurement for each subchannel. An initial sub carrier is allocated to each subchannel, and a quality metric measured. Subsequent subcarriers are allocated in dependence upon the quality measurement for each subchannel. The subchannel with the lowest quality measurement receives the first allocation, and the subchannel with the highest quality measurement receives the last allocation. The subsequent allocation is repeated, following a re-sort of the subchannel quality measurements, until all of the subcarriers are allocated.

    摘要翻译： 在多用户通信系统中，使用每个子信道的质量测量将副载波分配给子信道。 将初始子载波分配给每个子信道，并测量质量度量。 依赖于每个子信道的质量测量来分配随后的子载波。 具有最低质量测量的子信道接收第一分配，并且具有最高质量测量的子信道接收最后的分配。 在对子信道质量测量进行重新排序之后，直到所有副载波被分配为止重复后续分配。

    摘要： A roof structure of a building that has a pair of rafter beams and a pair of eave struts extending between and connected to the rafter beams includes a plurality of first banding strips. The first banding strips have opposite distal ends extending between and connected to the rafter beams. A plurality of second banding strips has opposite distal ends extending between and connected to the eave struts. A support sheet is supported on the first and second banding strips, and a shock absorbing member is attached between the support sheet and one of the rafter beams or the eave struts.
