摘要： A wireless communication apparatus is disclosed. A transmitting device transmits a first aggregation frame in which first transmission data frames are aggregated. A measuring device measures a number value of retransmission of each of the first transmission data frames. A storage stores a limiting value of the number value of retransmission. A determination device determines whether the number value of retransmission of each of the first transmission data frames exceeds the limiting value. A transmission buffer buffers the first transmission data frames for which it is determined that the number value of retransmission does not exceed the limiting value, and discards the first transmission data frames for which it is determined that the number value of retransmission exceeds the limiting value, of the first transmission data frames. A retransmitting device retransmits the first aggregation frame in which the first transmission data frames buffered in the transmission buffer are aggregated.

摘要： A physical header detecting unit detects a physical header from a received signal in which a first received signal intensity of a first channel or a second received signal intensity of a second channel exceeds a first threshold value. A first carrier sense unit determines that a carrier is detected when the physical header is detected. A second carrier sense unit determines whether a carrier is detected by determining whether the first or second received signal intensity exceeds a second threshold value when a physical header is not detected. A control unit controls the second carrier sense unit such that the second threshold value is lowered to temporarily increase the sensitivity of carrier sense when the second carrier sense unit performs carrier sense regarding the second channel.

摘要： An optical fiber is rolled by a swing motion of a swing guide roller in order to impart a predetermined twist to it effectively, and its polarization dispersion is suppressed equivalently as in a perfectly circular concentric optical fiber. A method of manufacturing such an optical fiber is also provided. As a swing guide roller swings, the optical fiber is rolled on its roller surface, so that a clockwise twist and a counterclockwise twist are imparted to the optical fiber alternately. At this time, the optical fiber is fitted in a V-shaped narrow groove formed at the central portion of the roller surface of a next-stage first stationary guide roller provided just beside the swing guide roller. Rolling of the optical fiber on the roller surface of the first stationary guide roller is suppressed, thereby helping smooth rolling of the optical fiber on the roller surface of the swing guide roller. As a result, a twist can be imparted to the optical fiber highly efficiently in accordance with the swing speed of the swing guide roller.
摘要翻译：通过摆动导向辊的摆动来卷绕光纤，以有效地赋予其预定的扭曲，并且其偏振色散被等同地抑制在完全圆形的同心光纤中。还提供了制造这种光纤的方法。当摆动导辊摆动时，光纤在其辊表面上滚动，从而交替地向光纤施加顺时针扭转和逆时针扭转。此时，光纤被装配在形成在位于摆动导向辊旁边的下一级第一静止导辊的辊面的中央部的V字状的狭槽中。抑制光纤在第一固定导辊的辊面上的滚动，从而有助于光纤在摆动导辊的辊面上的平滑滚动。结果，可以根据回转导辊的摆动速度高效率地赋予光纤扭转。
