    • An optical article includes an antireflection coating that is configured from alternately laminated n+1 low-refractive-index layers and n high-refractive-index layers (where n is an integer of 2 or more) . At least one of the n high-refractive-index layers is a first-type layer formed by vapor deposition using only a first deposition source that includes zirconium oxide as the main component. The remaining layers) in the n high-refractive-index layers is a second-type layer (s) formed by vapor deposition using only a second deposition source that includes titanium oxide as the main component. The n+1 low-refractive-index layers are third-type layers formed by vapor deposition using only a third deposition source that includes silicon oxide as the main component. The proportion of the total thickness of the second-type layer (s) in the total thickness of the n high-refractive-index layers is from 15% to 90%.
    • 光学制品包括由交替层叠的n + 1个低折射率层和n个高折射率层(其中n为2以上的整数)构成的防反射膜。 n个高折射率层中的至少一个是通过仅使用包含氧化锆作为主要成分的第一沉积源的气相沉积形成的第一类型层。 n个高折射率层中的剩余层是通过仅使用包括氧化钛作为主要成分的第二沉积源的气相沉积形成的第二类型层。 n + 1低折射率层是仅使用包括氧化硅作为主要成分的第三沉积源的气相沉积形成的第三类型层。 第二类层的总厚度在n个高折射率层的总厚度中的比例为15%至90%。

    • On the transmitting side, a decision is made as to whether to add pilot symbols which are separate from basic pilot symbols, to frames, based on the propagation path state, and when symbols are added, control symbols comprising information relating to the additional pilot symbols are generated, and frames comprising basic pilot symbols, control symbols, additional pilot symbols, and data symbols are assembled and transmitted. On the receiving side, control symbols included in the received frames are demodulated, and a judgment is made as to whether additional pilot symbols are included in the received frames based on the control symbol information, and if additional pilot symbols are included, the additional pilot symbols are used to estimate the propagation path, and the propagation path estimation value is used to demodulate data symbols.
    • 在发送侧,基于传播路径状态,判定是否将与基本导频符号分离的导频符号添加到帧,以及当添加符号时,包括与附加导频符号相关的信息的控制符号 并且组合并发送包括基本导频符号,控制符号,附加导频符号和数据符号的帧。 在接收侧,解调包含在接收帧中的控制符号,并且基于控制符号信息判断附加导频符号是否包含在接收帧中,并且如果附加导频符号被包括,则附加导频 使用符号来估计传播路径,并且传播路径估计值用于解调数据符号。
