RRU data merging system and method based on reconfigurable time domain filter

Abstract

The invention discloses an RRU data merging system based on a reconfigurable time domain filter, and the system comprises a data receiving end, a data screening module, a database, a data merging module and an RRU radio frequency unit. The operation method of the data merging system comprises the following steps: enabling the data receiving end to integrate the received information, converting the information into data, caches the data, and transmitting the data to the RRU radio frequency unit; screening the cached data through software, integrating and merging the initial data in the database and the data after time domain reconfiguration through the software and a processor, transmitting the merged data to an RRU radio frequency unit through a data line, and converting the data into information by the RRU radio frequency unit and transmitting the information. According to the invention, the data is transmitted into the database again after being subjected to time domain reconfiguration through the time domain reconfiguration module, and the data in the database is merged again, so that the loss of demodulation performance of the filter can be reduced, meanwhile, the load of the filter during working can be reduced, and the service life of the filter can be prolonged.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to a system and method for merging RRU data based on a reconfigurable time-domain filter. Background technique [0002] A filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter the frequency point of a specific frequency in the power line or frequencies other than this frequency point to obtain a power signal of a specific frequency or eliminate a power signal of a specific frequency. [0003] A filter is a frequency-selective device that allows specific frequency components in a signal to pass while greatly attenuating other frequency components. Utilizing this frequency selection function of the filter, it is possible to filter out interference noise or perform spectrum analysis. In other words, any device or system that can pass specific frequency components in a signal while greatly attenuating or suppressing other frequen...

Problems solved by technology

[0004] When merging data, the solutions in the prior art are basically the following two types: 1. Do simple time-domain data addition processing; 2. Do cross-correlation calculations on multi-channel received data, and frequency domain data According to the energy calculation of the specific threshold value, for the signal exceeding the threshold, the data is retained, the others are cleared to zero, and finally merged. Under high load conditions, resulting in reduced filter life
