Vector network analyzer applique for adaptive communications in wireless networks

A test signal generator at a transmitter station and a facsimile generator at a receiver station go through an acquisition and tracking process which aligns the two signals so that a logical processor can compute the frequency transfer function of the entire propagation path for use in an adaptive, concurrently sent communication signal. The frequency transfer function is conveyed back to the transmit end via a control channel permitting an adaptivity function at the transmit end to influence subsequent selection of communication parameters, among which are typically transmitted data rate, selection of modulation, selection of forward error correcting coding, and selection of frequency band for transmission. The same measurement is conveyed to an adaptivity function at the receive end for use in the communications receiver to select demodulator variables such as gain control, and equalization of amplitude and phase, versus frequency. The adaptivity function also permits interspersing of reverse-direction communications over the same frequency bands in a time-share mode between forward-direction and reverse-direction communication with the measurement signals having to be transmitted in only one direction. An alternate embodiment invention of this type is described which is additionally useful for mobile communications channels. Another variation embodiment is described for pure propagation measurements only, absent conveyance of end-user information.

A kind of lumen stent delivery system

The invention discloses a lumen bracket conveying system. The system comprises a handle shell and a linkage mechanism, wherein a sheath pipe, an inner core pipe and a push pipe are parallelly arranged on the handle shell; a sheath joint for connecting the sheath pipe and driving the sheath pipe to move and a push pipe joint for connecting the push pipe and driving the push pipe to move are arranged in the handle shell; the linkage mechanism is used for driving the sheath pipe and the push pipe synchronously through the sheath joint and the push pipe joint; the sheath joint and the push pipe joint are moved in opposite directions; and the ratio of the movement speed of the push pipe joint to the movement speed of the sheath joint is equal to the ratio of the axial shortening amount of a conveyed bracket to the natural length of the bracket. The conveying system has a bracket shortening self-adaption function; and due to the adoption of compensation movement of the push pipe and the inner core pipe towards a far end, the defect of the shortening rate of the bracket is overcome, so that the bracket cannot be influenced by the axial tension and drawing effects of the conveying system, the accurate positioning of the bracket is ensured, and the problem of damages of the bracket to the pipe wall of a human body is solved.
