Device and method for enhancing multi-channel transmitter covering

Abstract

The invention discloses a device and a method for enhancing multi-channel transmitter covering. The device comprises a baseband control module, a digital-analog conversion module, an up frequency conversion module, a combiner module and a power detection module. The method comprises the following steps: utilizing each channel opened by a combiner switch to receive inputted digital signals and respectively carry out modulation and phase modulation processing to send, wherein the received digital signals of each channel opened by the combiner switch are same; receiving the processed digital signals sent by each channel and respectively converting the digital signals into analog signals to be sent; receiving the analog signals sent by each channel, and respectively carrying out up conversion processing for the analog signals to obtain radio-frequency signals to be sent; receiving the radio-frequency signals sent by each channel, and stacking the radio-frequency signals of each channel opened by the combiner switch to be outputted; and real-time detecting the power value of the outputted signals to report the detecting results. The method combines the multi-channel signals of the multi-channel transmitter into a carrier wave to obtain different-level transmission gain.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a device and method for enhancing the coverage of a multi-channel transmitter. Background technique [0002] The multi-channel transmitter is to integrate two or more transmitters in one base station, so as to increase the capacity of the system and improve the system density. For the GSM (Global System for Mobile Communications, Global System for Mobile Communications) system, each channel can support a maximum of 8 users, two channels can support a maximum of 16 users, three channels can support a maximum of 24 users, and so on. In densely populated areas, multi-channel transmitters are widely used due to their large capacity and high density. In rural areas where there are few users, improving the coverage of transmitters and reducing network construction costs are more concerned by operators. At present, the traditional method of increasing the downlink coverage area ...

AI Technical Summary

Problems solved by technology

[0004] Due to the different equipment used in the occasions where few users need a large coverage area and the occasions where many users require high system density, the methods used in the prior art cannot meet the needs of high versatility of equipment and convenient network construction required by operators.
