    摘要: A method and device for receiving a non-synchronous signal in an Orthogonal Frequency Division Multiple Access (OFDMA) system are provided. The method includes the following steps. Fourier transform is performed on a received first time domain signal to acquire a corresponding frequency domain signal. A sub-carrier occupied by a band of a non-synchronous signal to be received in the frequency domain signal is set to zero, inverse Fourier transform is performed on the frequency domain signal to acquire a second time domain signal, and the second time domain signal is subtracted from the first time domain signal. Or, the sub-carrier other than the sub-carrier occupied by the band of the non-synchronous signal to be received in the frequency domain signal is set to zero, and inverse Fourier transform is performed on the frequency domain signal to acquire a time domain received signal corresponding to the band of the non-synchronous signal.

    摘要: A typing support is provided as a part of a typing station including a keyboard. The typing support includes a frame having a track and a keyboard support for engagement with a keyboard, a pair of wrist supports, and mounting members on which the wrist supports are carried. The mounting members provide support for the wrists of the typist which allow pivotal movement of one and preferably both hands during typing, and also translational movement along the longitudinal axis of the track. At least one of the wrist supports may be retained in a stationary position relative to the track by a retainer. The relative height or inclination of the keyboard can be adjusted by adjustment feet. The keyboard support may include a support member which pivots relative to a base to adjust the height of the keyboard received thereon, and may also keep a sheet of paper or the like in an upright position for viewing during typing.

    摘要: A user access method and system are provided. The method includes the following steps. After the connection between a terminal and an access network AN is disconnected, a media access control identifier MAC ID is preserved in a predetermined time period. If the terminal initiates an access to the AN within the predetermined time period, the MAC ID is used by the terminal for accessing the AN. The system of the present embodiment includes a terminal and an AN. According to the method and system, the access time initiated by the terminal is reduced, the access collision is avoided, and the system performance is greatly enhanced.
