Abstract

The invention discloses a method for detecting spatial thermal noise at the position of antenna of base station and a device thereof. The method includes that a detection frequency band in idle state in the working frequency band of a transceiver in the base station is utilized to create a base band processing link, the created base band processing link is utilized to filter a mixed signal containing carrier signal and spatial thermal noise, so as to remove the carrier information in the mixed signal, and the signal intensity of the obtained spatial thermal noise is detected, thus achieving the aim of detecting the signal intensity of spatial thermal noise in detection frequency band.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and equipment for detecting spatial thermal noise where a base station antenna is located within a working frequency band. Background technique [0002] The base station system includes a duplexer and a transceiver, wherein the transceiver includes two parts, a radio frequency analog circuit and a data intermediate frequency circuit, and the received signal strength indicator (Received Signal Strength Indicator, RSSI) of the signal received in the space near the base station antenna can be Detected in the digital IF circuit in the reverse receiver link of the transceiver. [0003] The detected RSSI includes the signal strength of two parts of the signal, one part is the signal strength of the carrier signal transmitted through the base station antenna, and the other part is the signal strength of the spatial thermal noise (also called floor noise) where the base station antenna...
