Embodiment Construction

[0029] The deployment of base stations in the driving environment of subways and air trains will affect the coverage of the received signal strength of the carriages, and will also affect the investment cost of the number of base stations deployed. For this reason, the present invention proposes a systematic deployment method of base stations along the track, with the goal of covering good signal quality, to achieve a systematic method of cell coverage design for base stations of subway trains.

[0030] For a clearer representation, the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] Such asfigure 1 , what the embodiment of the present invention provides is a kind of subway base station deployment planning method based on multi-carrier modulation broadband technology, it comprises:

[0032] Step S10: setting the target transmission rate of the subway base station;

[0033] Step S11: setting multi-subcarrier broadband...

Abstract

The invention discloses a subway base station arrangement planning method based on a multi-carrier modulation broadband technology. The method comprises the following steps: step S10, setting a target transmission rate of a subway base station; step S11, setting parameters of a multi-subcarrier broadband system; step 12, calculating a received signal sensitivity threshold value and a bit transmission bit rate threshold value of the modulation configuration and coding rate combination; step 13, setting environmental parameters; step 14, calculating a link budget; step 15, calculating the cell size, the base station arrangement number and the data transmission rate; and S16, detecting whether the data transmission rate meets the target transmission rate or not, and if the data transmission rate meets the target transmission rate, finishing planning. According to the subway base station arrangement planning method based on the multi-carrier modulation broadband technology, systematic arrangement of subway base stations is realized.

Description

technical field [0001] The invention relates to the field of subway communication, in particular to a method for planning the deployment of subway base stations based on multi-carrier modulation broadband technology. Background technique [0002] The communication system plays an important role in the overall service of subway, urban light rail, and monorail transportation. For the sake of convenience, this article will refer to subway, urban light rail, and monorail transportation as subway. In the subway traffic in operation in my country, most of its wireless communication systems still use the "terrestrial trunked radio (TErrestrial Trunked RAdio, TETRA)" system, which includes the "MTR" in Hong Kong, China, and the "Taipei MRT" in Taiwan, China. , Kaohsiung MRT" and so on. The European railway radio communication system applied to railway trains is mainly based on two major systems: TETRA and GSM-R (Global System for Mobile Communications Railway, GSM-R). Although TETR...
