Example Embodiment

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0043] Since the repeater provided in the prior art uses a preset fixed frequency band and gain to provide two-way signal amplification, the quality of the amplified signal is poor, it will interfere with the base station network, and it cannot be flexibly equipped with FDD or FDD of different operators. Technical issues of TDD channel allocation.

[0044] In order to solve the above technical problems, the present invention proposes an intelligent repeater and a communication method based on the intelligent repeater, such as figure 1 As shown, the RF coupler uses an N×N MIMO external antenna to r...

Abstract

The invention is suitable for the mobile communication field and provides an intelligent repeater and a communication method based on the intelligent repeater. The intelligent repeater comprises an N*N type MIMO external antenna, a radio frequency coupler, a control circuit, N paths of repeater circuits and an N*N type MIMO internal antenna. The control circuit is used for carrying out real-time detection according to customizable preset rules and screening out an optimum LTE channel frequency band coupled into downward signals, dynamically adjusting an amplification gain according to intensity of signals in the optimum LTE channel frequency band, and sending a control instruction to the N paths of repeater circuits in real time; and the N paths of repeater circuits are used for filteringsignals, except the signals in the optimum LTE channel frequency band, in uplink signals and the downlink signals, carrying out amplification on the signals in the optimum LTE channel frequency band according to the amplification gain obtained after dynamic adjustment, and then, outputting the signals. The method can effectively ensure quality of the output signals obtained after being amplified by the repeater, and prevent over-strong signals from interfering a base station network.

Description

technical field [0001] The invention belongs to the field of mobile communication, in particular to an intelligent repeater and a communication method based on the intelligent repeater. Background technique [0002] The repeater is a kind of untrusted signal repeater, and its main function is to amplify the signal in wireless communication transmission. In the downlink, the repeater receives the signal through the forward antenna, filters the received signal through a band-pass filter, and then amplifies the filtered signal through the power amplifier and transmits it to the coverage area through the rear antenna to achieve Signal transmission between base station and mobile station. [0003] The existing repeater design generally adopts the method of preset fixed frequency band and gain to provide two-way signal amplification function to solve the problem of extended coverage of operators and small and medium-sized enterprises in areas with insufficient 4G signal coverage....
