    • Provided is an apparatus for modulation in a base station with a smart antenna. The smart antenna system has many advantages that it is possible to deal with the large volume of subscribers; communication quality is increased; etc. However, the smart antenna system has disadvantages that cost is increased due to many antennas; base station transceivers have a complicated structure due to multiple antennas per base station; it is too complicated to manage resource and channel allocation; there is required compatibility with a conventional system; etc. The present invention provides an apparatus for modulation in a base station with a smart antenna, which can solve the foregoing problems by employing a modulator using a time division multiplexing method, a sector beam selector, and a TX beam former, thereby providing good compatibility regardless of a change in the number of base station sectors and the number of antennas.
    • 提供了一种用于在具有智能天线的基站中进行调制的装置。 智能天线系统具有许多优点,可以处理大量用户; 通信质量提高; 然而,智能天线系统具有由于许多天线而导致成本增加的缺点; 基站收发机由于每个基站的多个天线而具有复杂的结构; 管理资源和渠道分配太复杂了; 需要与常规系统的兼容性; 本发明提供了一种用于具有智能天线的基站中的调制装置,其可以通过采用使用时分复用方法的调制器,扇区波束选择器和TX波束形成器来解决上述问题,从而提供良好的 兼容性,而不管基站扇区数量和天线数量的变化。

    • A headband mainly used for headwear and constructed by properly weaving 100% nylon combustible yarn. Having no polyurethane, the headband is woven to single ply or two-ply without an additional stitched portion, and exhibits good elasticity as a whole through the napped, felt-like structure of the textile. The circumferential stretch direction of the headband also provides excellent sweat absorption capability. With this construction a wide range of automatic size adjustment is obtained without imposing undue elastic pressure on the wearer such that the cap and headband are comfortable for extended periods of wear.
    • 头带主要用于头饰,通过适当编织100%尼龙可燃纱线构成。 没有聚氨酯,头带被编织成单层或双层而没有附加的缝合部分,并且通过纺织品的起绒的毡状结构整体呈现出良好的弹性。 头带的周向拉伸方向也具有优异的吸汗能力。 利用这种结构,可以获得宽范围的自动尺寸调整,而不会对佩戴者造成不适当的弹性压力,使得帽和头带在长时间的磨损时舒适。
