Abstract

SISTEMA DE RELÉ DISTRIBUÍDO DE PADRÃO LTE, MÉTODO DE SUPRESSÃO DE RUÍDO DE ENLACE ASCENDENTE E DISPOSITIVO DE COMPUTADOR. Trata-se de um sistema de relé distribuído de padrão LTE e um método de supressão de ruído de enlace ascendente. O sistema compreende uma unidade de detecção de sinal de enlace ascendente e uma unidade de transmissão de sinal de enlace ascendente. Tanto uma extremidade de detecção da unidade de detecção de sinal de enlace ascendente quanto uma extremidade de entrada da unidade de transmissão de sinal de enlace ascendente são conectadas a uma extremidade de recebimento de sinal de enlace ascendente do sistema de relé distribuído de padrão LTE. Uma extremidade de saída da unidade de transmissão de sinal de enlace ascendente é conectada, por meio de uma unidade de atenuação de sinal, a uma estação-base. Uma extremidade de controle da unidade de detecção de sinal de enlace ascendente é conectada à unidade de atenuação de sinal de modo a disparar a unidade de atenuação de sinal para ligar quando a unidade de detecção de sinal de enlace ascendente detectar um sinal de enlace ascendente alvo. A unidade de atenuação de sinal é usada para restaurar a atenuação por um tempo predeterminado atrasado depois de ser ligada.LTE STANDARD DISTRIBUTED RELAY SYSTEM, UPLOAD NOISE SUPPRESSION METHOD AND COMPUTER DEVICE. It is an LTE-standard distributed relay system and an uplink noise suppression method. The system comprises an uplink signal detection unit and an uplink signal transmission unit. Both a detection end of the uplink signal detection unit and an input end of the uplink signal transmission unit are connected to an uplink signal receiving end of the LTE standard distributed relay system. An output end of the uplink signal transmission unit is connected, via a signal attenuation unit, to a base station. A control end of the uplink signal detection unit is connected to the signal attenuation unit so as to trigger the signal attenuation unit to turn on when the uplink signal detection unit detects a target uplink signal . The signal attenuation unit is used to restore attenuation for a predetermined time delay after being turned on.
