Abstract: The invention discloses a water and gas dual-purpose electric erection aid which comprises a vacuum barrel and a device bin arranged at the top of the vacuum barrel, wherein the device bin comprises a seal cover which covers one end of the vacuum barrel and a pump valve pipeline mechanism arranged in the seal cover and used for vacuumizing or releasing vacuum of the interior of the vacuum barrel; the device bin is fixedly installed with a button control assembly via a support frame, and the inner wall of the open groove is tightly attached to the outer wall of the button control assembly; and the pump valve pipeline mechanism is communicated with two connection ports formed in the top end of the vacuum barrel and a vent cover fixedly arranged on the seal cover through a connecting pipe. The erection aid not only can be used in air, but also can be used underwater.

Abstract: A method of channel estimation of a mobile communication system based on a time division pilot field is disclosed. The method uses a transmitting end that transmits a time division pilot sequence having a cyclic prefix and a receiving end that transforms the time division pilot sequence into frequency domain using a fast Fourier transform module. Channel estimation is performed to obtain a channel frequency response estimation result. The receiving end transforms the channel frequency response estimation result back into time domain and obtains a channel impulse response estimation result.
