Problems solved by technology

Similarly, the input noise of the mobile terminal will also be affected by the downlink output noise floor of the remote coverage system. When the downlink output noise floor of the remote coverage system increases, the input noise of the mobile terminal will also increase, thereby reducing the receiving sensitivity of the mobile terminal.
The noise introduced by the downlink input terminal of the remote coverage system is amplified by the remote coverage system and transmitted to the downlink output terminal of the remote coverage system, making the downlink output noise floor larger
Moreover, the greater the downlink gain of the remote coverage system, the greater the impact on the downlink output noise floor
The lifting effect of the noise floor affects the receiving effect of the base station and the mobile terminal, which is more likely to occur in the remote coverage system
Because in the remote coverage system, there is an active remote unit between the remote relay end and the remote radio unit, the active remote unit is easy to introduce noise, thereby increasing the noise of the remote relay end in the remote coverage system. Uplink output noise floor and downlink output noise floor of remote RF unit

Abstract

The invention discloses a noise floor suppression method for a remote coverage system. The noise floor suppression method comprises the following steps of detecting the output power of an active remote unit in the remote coverage system; according to a detection result, adjusting the output power of the active remote unit within a preset range. The invention also discloses a noise floor suppression device for the remote coverage system. The noise floor suppression device comprises an output power detection module and an output power adjustment module. The noise floor suppression method and the noise floor suppression device for the remote coverage system can be used for automatically suppressing noise floor of the remote coverage system. By presetting a control range for the output power of the active remote unit, the output power of the active remote unit is adjusted in real time; therefore the output noise floor of the remote coverage system is controlled in a reasonable range, and the influence on the receiving sensitivity of a base station and a mobile terminal is reduced. The noise floor suppression method and the noise floor suppression device for the remote coverage system are easy to implement, convenient to use, low in cost and convenient to promote and apply.

Description

technical field [0001] The invention relates to the technical field of noise suppression, in particular to a noise suppression method for a remote coverage system and a noise suppression device for a remote coverage system. Background technique [0002] After the remote coverage system is introduced into the wireless coverage access system, the input noise of the base station will be affected by the uplink output noise floor of the remote coverage system. When the uplink output noise floor of the remote coverage system increases, the input noise of the base station will increase accordingly, thereby reducing the receiving sensitivity of the base station. The noise introduced by the uplink input terminal of the remote coverage system is amplified by the remote coverage system and transmitted to the uplink output terminal of the remote coverage system, making the uplink output noise floor larger. The greater the uplink gain of the remote coverage system, the greater the impac...
