Signal processing method, system and equipment

Abstract

The invention discloses a signal processing method, system and equipment, and the method comprises the steps: receiving a multi-band transmission signal, and determining a single radio frequency remote channel for transmitting the multi-band transmission signal; performing digital conversion on the multi-band transmission signal to obtain a multi-band radio frequency signal; frequency conversion and amplification are carried out on the multi-band radio frequency signals, so that the total transmitting power value of the multi-band radio frequency signals is not greater than the output power value of a single radio remote channel; and transmitting the multi-band radio frequency signals through a single radio frequency remote channel. The frequency conversion and amplification of the transmitted signal are carried out in the remote radio frequency equipment, and the power required by the transmission of the transmitted signal is adjusted, so that the multi-band and multi-system signals can be transmitted through a single remote radio frequency channel, and the flexibility of the frequency band combination of the remote radio frequency equipment is improved; while the networking requirements of multiple operators are met, the size of the multi-frequency radio remote device is reduced, and the system construction cost is further reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a signal processing method, system and equipment. Background technique [0002] With the rapid development of mobile communication technology, mobile Internet and high-bandwidth data services have grown explosively. In the current mobile network, most of the services take place indoors, so indoor mobile network coverage will be more important. In the current mobile communication system, the network coverage mode in the indoor scene mostly adopts the distributed base station signal of the indoor baseband unit (Building Baseband Unit, BBU) + radio remote unit (Radio Remote Unit, RRU). However, a single-frequency remote radio unit (RRU) device can only support the transmission and reception of radio frequency signals in one frequency band, and a multi-frequency RRU device also needs to be assembled from two or more RRU devices of different frequency bands, result...

AI Technical Summary

Problems solved by technology

However, a single-frequency remote radio unit (RRU) device can only support the transmission and reception of radio frequency signals in one frequency band, and a multi-frequency RRU device also needs to be assembled from two or more RRU devices of different frequency bands, resulting in this multi-frequency The frequency band combination flexibility of RRU equipment is poor, making it difficult to meet the networking needs of multiple operators

At the same time, under the background of multi-network integration and co-construction and sharing, the multi-frequency RRU system assembled by two or more RRU devices of different frequency bands is large in size, which makes the cost of building a multi-frequency RRU system relatively high.
