Abstract

Система и способ фильтрации сигнала, которые можно использовать совместно с ретранслятором или входным каскадом базовой станции. Система может включать в себя аналогово-цифровой преобразователь, выполненный с возможностью выборки принимаемого сигнала и получения потока данных, соответствующего принимаемому сигналу в области времени, блок фильтрации, имеющий один или больше элементов цифрового фильтра, в котором каждый из указанных одного или больше элементов фильтра выполнен с возможностью фильтрации одного или больше наборов полос частот, ассоциированных с одним или больше каналами передачи данных, и контроллер, выполненный с возможностью конфигурирования указанных одного или больше элементов цифрового фильтра на основе параметров, сохраненных в базе данных и/или на основе параметров, принятых через модем.A system and method of filtering a signal that can be used in conjunction with a repeater or an input stage of a base station. The system may include an analog-to-digital converter, configured to sample the received signal and receive a data stream corresponding to the received signal in the time domain, a filtering unit having one or more digital filter elements, in which each of said one or more filter elements with the ability to filter one or more sets of frequency bands associated with one or more data channels, and a controller configured to configure those indicated in one or more digital filter elements based on the parameters stored in the database and / or based on the parameters received via the modem.
