Embodiment Construction

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0034] In order to better explain the present invention, the antenna calibration and the position of the antenna calibration time slot are firstly introduced. Specifically, when the antenna is transmitting for calibration, the calibration channel is in the receiving state, and the working channel is in the transmitting state. The working channel sends a calibration sequence at a fixed position in the time slot, and the calibration channel uses the received calibration sequence to calculate the phase and amplitude deviation of each channe...

Abstract

The embodiment of the invention provides a method for dynamically regulating an antenna calibration position, comprising the following steps: measuring the interference power intensity Pinter of an initial antenna calibration TS (time slot) position Pos1 in accordance with signals eac received by the initial antenna calibration TS position Pos1; comparing the interference power intensity Pinter with the maximum transmission power Pmax of calibration sequences, and selecting the antenna calibration TS position in accordance with the comparison result; and according to the selected antenna calibration TS position, transmitting the calibration sequences to carry out the antenna calibration. The embodiment of the invention also provides a device for dynamically regulating the antenna calibration position, comprising a measurement module, a selection module and a calibration module. The method and device provided by the invention can be used to improve the antenna calibration accuracy, prevent the frequent warning of the antenna calibration and solve the problem that the intelligent antenna calibration is interfered.
