Embodiment 1

[0022] see figure 1 , the embodiment of the present invention provides a repeater, including: a radio frequency module 20 and a repeater ID (Identification, identifier) ​​generation module 30.

[0023] The radio frequency module 20 is used to realize the enhancement and forwarding of digital broadcast signals between the base station and the mobile terminal.

[0024] Like the traditional broadcast repeater, the radio frequency module 20 mainly realizes the enhancement and forwarding function of the digital broadcast signal between the base station and the mobile terminal. Specifically, see figure 2 , the radio frequency module 20 includes: a donor antenna 201, a first bandpass filter 202, a low noise power amplifier module 203, a power amplifier (PA, Power Amplificatory) module 204, a second bandpass filter 205, a service antenna 206, a control module 207 and power module 208 .

[0025] Specifically, in the process of the base station transmitting digital broadcast signals...

Embodiment 2

[0043] In the present embodiment, the coverage area of ​​the repeater is divided into N sub-coverage areas, and a corresponding sub-coverage area ID is set for each sub-coverage area, and a specific area and its position can be determined by each sub-coverage area ID, wherein N It is a positive integer, and the specific value of N can be set according to the actual application situation. see figure 1 , the embodiment of the present invention provides a repeater, the repeater includes: a radio frequency module 40 and a repeater ID generating module 50 .

[0044] The radio frequency module 40 is used to realize the enhancement and forwarding of digital broadcast signals between the base station and the mobile terminal.

[0045] see image 3 , the radio frequency module 40 includes: a donor antenna 401, a first bandpass filter 402, a low noise power amplifier module 403, a power amplifier module 404, a second bandpass filter 405, N serving antennas 406, a control module 407 and a...

Embodiment 3

[0066] see Figure 4 , Figure 5 with Image 6 , the embodiment of the present invention provides a repeater, including: a radio frequency module 60 and a repeater ID generating module 70 .

[0067] The radio frequency module 60 is used for enhancing and forwarding communication signals between the base station and the mobile terminal.

[0068] Like the traditional communication repeater, the radio frequency module 60 mainly realizes the enhancement and forwarding function of the communication signal between the base station and the mobile terminal. Specifically, see Figure 4 , Figure 5 with Image 6 , the radio frequency module 60 includes: a donor antenna 601, a first duplexer 602, a downlink low noise amplifier 603, a downlink filter 604, a downlink driver amplifier 605, a downlink high power amplifier 606, a control module 607, a second duplexer 608, A service antenna 609 , an uplink low noise amplifier 610 , an uplink filter 611 , an uplink driver amplifier 612 , ...

Abstract

The invention discloses a repeater and a mobile positioning system and belongs to the technical field of mobile digital TV broadcast. The repeater comprises a radio frequency module and a repeater ID generating module, wherein the radio frequency module comprises a donor antenna and a service antenna. An ID is added to the repeater through the repeater ID generating module, so that a mobile terminal positioned in a coverage area of the repeater can acquire the ID of the repeater, determine the position of the repeater according to the ID of the repeater and position the mobile terminal according to the position of the repeater. Therefore, positioning deviation of the mobile terminal is reduced and precise positioning for the mobile terminal is realized.

Description

technical field [0001] The invention relates to the technical field of mobile digital broadcasting and television, in particular to a repeater and a mobile positioning system. Background technique [0002] In the field of mobile digital broadcasting and television, the mobile terminal positioning technology has been widely used because it can realize the positioning of the mobile terminal and obtain the location information of the mobile terminal. The existing mobile terminal positioning technology mainly uses the pseudo-range measurement between the antenna of the base station transmitter and the antenna of the mobile terminal to calculate the position of the mobile terminal. However, in the existing mobile digital broadcast TV system, in order to ensure that the mobile terminal can normally receive the broadcast signal from the base station, repeaters are set up in some areas that the base station cannot directly cover. The station transmits the signal between the base st...
