    • Improving the accuracy of estimation of channel responses in receiving signals from a plurality of antennas is disclosed. A transmitting device of a base station includes a preamble A generating unit 010, a preamble B generating unit 011, phase rotating units 012 and 013, multiplexing units 014 and 015, an forward error correction coding unit 016, an S/P converting unit 017, a mapping unit 018, a changeover switch 019, IDFT (or IFFT) units 020 and 026, P/S converting units 021 and 027, GI (Guard Interval) inserting units 022 and 028, D/A converting units 023 and 029, radio transmitting units 024 and 030 and antenna units 025 and 031. In the preamble A generating unit 010 and the preamble B generating unit 011, a preamble A and a preamble B (see the packet format in FIG. 1) are generated, respectively. The preamble A is outputted to the multiplexing units 014 and 015, while the preamble B is outputted to the phase rotating units 012 and 013. The phase rotating units 012 and 013 to which the preamble B has been inputted give continuous phase rotation to subcarriers of the preamble B. In the transmitting device of the base station according to this embodiment, the phase rotating unit 012 does not give phase rotation, but only the phase rotating unit 013 gives phase rotation to the preamble B.

    • A communication system, a communicating method and a base station are provided. When a base station generates an FCM, the base station detects the use rate of a transmission buffer and decides how slots of a frame of an uplink channel are structured. When the use rate of the transmission buffer is high, the base station designates the number of ACTSs to 0 so that the base station does not accept registration requests and so forth from mobile stations. When the use rate of the transmission buffer is low, the base station designates the number of ACTSs to 1. When the number of mobile stations is large as in a large convention hall, the base station generates TDMA frames each of which has only ACTSs. The base station can decide the number of ATCSs corresponding to the probability of which registration requests and so forth from mobile stations collide.
    • 提供通信系统,通信方法和基站。 当基站生成FCM时,基站检测发送缓冲器的使用率,并且确定上行链路信道的帧的时隙如何被构造。 当发送缓冲器的使用率高时,基站将ACTS的数量指定为0,使得基站不接收来自移动台的注册请求等。 当发送缓冲器的使用率低时,基站将ACTS的数量指定为1.当大型会议厅中的移动站的数量较多时,基站产生每个仅具有ACTS的TDMA帧。 基站可以根据来自移动台的注册请求等的概率对应的ATCS的数量来决定。

    • An electrostatically driven latchable actuator system has an actuator and a pair of side effectors on opposite ends of the actuator. The actuator is resiliently supported to a substrate and is movable along a linear axis between two operative positions as being electrically attracted to one of the side effectors. A latch mechanism is provided to mechanically latch the actuator at either of the operative positions. The side effectors are movably towards and away from the actuator along the linear axis between a normal position and a shifted position close to the actuator. Both of the side effectors are also resiliently supported to the substrate to be movable towards the actuator by being electrostatically attracted thereto and away from the actuator by resiliency. The moving side effector is interlocked to the latch mechanism through a mechanical link so as to unlatch the actuator in response to one of the side effectors being attracted to the actuator, and allow the actuator to move from one operative position to the other operative position to be again latched thereat.
    • 静电驱动的可闩锁致动器系统在致动器的相对端具有致动器和一对副作用器。 致动器被弹性地支撑到基板上,并且可以沿着线性轴线在两个操作位置之间移动,从而被电吸引到一个副作用器。 提供闩锁机构以在执行位置的任一位置机械地闩锁致动器。 副作用器可沿着线性轴线在致动器之间朝向和远离致动器移动,在正常位置和靠近致动器的移位位置之间。 两个副作用器也被弹性地支撑到基板上,以通过静电吸引到致动器并且通过弹性远离致动器而朝向致动器移动。 运动侧执行器通过机械连杆与闩锁机构互锁,以响应于一个副作用器被吸引到致动器而解锁致动器,并允许致动器从一个操作位置移动到另一操作位置, 再次被锁在那里。
