Method, device and equipment for improving equipment blocking index

Abstract

The invention relates to a method, device and equipment for improving equipment blocking index. Among them, the method of improving the device blocking index is based on the received signal bandwidth and instantaneous working bandwidth of the device, detects the signal strength of the in-band signal and the out-of-band signal, and performs automatic gain control to obtain the in-band attenuation signal and attenuation value; the received signal bandwidth and The instantaneous working bandwidth is configured according to the network standard; the signal strength of the out-of-band signal and the signal strength of the in-band signal are detected without increasing the BOM cost or affecting the normal operation of the link, ensuring the independence of equipment work and the flexibility of the system According to the attenuation value and the pre-stored gain distribution table, the in-band attenuation signal is amplified to obtain the in-band amplified signal; it can effectively ensure the coverage quality of the in-band signal, improve the blocking performance of the system and the self-management ability of the equipment, and reduce manual intervention.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method, device and equipment for improving equipment blocking index. Background technique [0002] The wireless repeater is a same-frequency amplification device, which refers to a device that couples signals through the donor antenna during wireless communication transmission and then amplifies them by frequency selection to increase the signal. Since the digital wireless repeater receives signals from space, it is bound to require the space signal to be as pure as possible; and in areas where base stations or signals are relatively dense, it is difficult to separate signals from different base stations or sectors, which may easily cause interference to the repeater. A typical situation is that the out-of-band signal coupled by the antenna is strong, which leads to serious attenuation at the front end of the device, blocks the power of useful signals, and affect...
